A '''workstation''' is a high-end [[microcomputer]] designed for technical or scientific applications. Intended primarily to be used by one person at a time, they are commonly connected to a [[local area network]] and run [[multi-user]] [[operating system]]s. The term ''workstation'' has also been used to refer to a [[mainframe computer]] terminal or a PC connected to a [[Computer network|network]]. |
|||
Workstations formerly offered higher performance than mainstream [[personal computer]]s, especially in [[Central processing unit|CPU]], [[Graphics processing unit|graphics]], memory, and multitasking. Workstations are optimized for the [[Visualization (graphics)|visualization]] and manipulation of different types of complex data such as 3D mechanical design, engineering simulations like [[computational fluid dynamics]], [[computer animation|animation]], [[video editing]], [[image editing]], [[medical imaging]], image rendering, [[computational science]], generating [[plot (graphics)| mathematical plots]], and [[software development]]. Typically, the [[Form factor (design)|form factor]] is that of a [[desktop computer]], which consists of a high-resolution display, a [[computer keyboard|keyboard]], and a [[Mouse (computer)|mouse]] at a minimum, but also offers multiple displays, [[graphics tablet]]s, and [[Computer mouse|3D mice]] for manipulating objects and navigating scenes. Workstations were the first segment of the computer market<ref>{{cite web|url=https://www.businesswire.com/news/home/20210623005540/en/Global-Personal-Computers-Market-Report-2021-to-2030---COVID-19-Impact-and-Recovery---ResearchAndMarkets.com |title=Global Personal Computers Market Report (2021 to 2030) - COVID-19 Impact and Recovery - ResearchAndMarkets.com |publisher=Business Wire |date=2021-06-23 |accessdate=2022-09-07}}</ref> to present advanced accessories, and collaboration tools like [[videoconferencing]].<ref name=":2" /> |

The increasing capabilities of mainstream PCs since the late 1990s have reduced distinction between the PCs and workstations.<ref>{{cite web |title=Workstation Computer |url=https://www.oidairweb.online/2021/06/workstation-computer.html |work=OIDair WEB |language=en |access-date=2021-12-05 |archive-date=2021-12-05 |archive-url=https://web.archive.org/web/20211205163525/https://www.oidairweb.online/2021/06/workstation-computer.html |url-status=dead }}</ref> Typical 1980s workstations have expensive proprietary hardware and operating systems to categorically distinguish from standardized PCs. From the 1990s and 2000s, [[IBM]]'s [[RS/6000]] and [[IntelliStation]] have [[RISC]]-based [[IBM Power microprocessors|POWER]] CPUs running [[AIX]], and its [[IBM PC Series]] and [[IBM Aptiva|Aptiva]] corporate and consumer PCs have Intel x86 CPUs. However, by the early 2000s, this difference largely disappeared, since workstations use highly [[Commoditization|commoditized]] hardware dominated by large PC vendors, such as [[Dell]], [[Hewlett-Packard]], and [[Fujitsu]], selling [[x86-64]] systems running [[Microsoft Windows|Windows]] or [[Linux]]. |
|||
==What makes a workstation?== |
|||
Today, consumer products such as PCs (and even [[game console]]s) use components that provide a reasonable cost for tasks that do not require heavy and sustained processing power. However, for timely engineering, medical, and graphics production tasks the workstation is hard to beat. |
|||
==History== |
|||
In the early 1980s, a high-end workstation had to meet the three Ms, the so-called "[[3M computer]]" had a '''M'''egabyte of memory, a '''M'''egapixel display (roughly 1000x1000), and a "[[megaflop|'''M'''egaFLOPS]]" compute performance (at least one million floating point instructions per second).<ref>RFC 782 defined the workstation environment more generally as ''hardware and software dedicated to serve a single user'', and that it provide for the use of additional shared resources.</ref> As limited as this seems today, it was at least an order of magnitude beyond the capacity of the personal computer of the time; the original 1981 [[IBM PC]] had 16 KB memory, a text-only display, and floating-point performance around 1 kiloFLOPS (30 kiloFLOPS with the optional 8087 math coprocessor). Other desirable features not found in desktop computers at that time included networking, graphics acceleration, and high-speed internal and peripheral data buses. |

===Origins and development=== |
|||
Another goal was to bring the price for such a system down under a "'''M'''egapenny", that is, less than $10,000; this was not achieved until the late 1980s, although many workstations, particularly mid-range or high-end still cost anywhere from $15,000 to $100,000 and over throughout the early to mid 1990s. |
|||
Workstations are older than the first [[personal computer]] (PC).<ref name="baran198902">{{Cite magazine |last=Baran |first=Nick |date=February 1989 |title=Two Worlds Converge |url=https://archive.org/details/eu_BYTE-1989-02_OCR/page/n284/mode/1up?view=theater |access-date=2024-10-08 |magazine=BYTE |pages=229-233}}</ref> The first computer that might qualify as a workstation is the [[IBM 1620]], a small scientific computer designed to be used interactively by a single person sitting at the console.<ref>{{cite web |title=IBM workstations |url=https://www.ibm.com/ibm/history/documents/pdf/emea.pdf |website=IBM}}</ref> It was introduced in 1959.<ref>{{cite web |date=2003-01-23 |title=IBM Archives: 1620 Data Processing System |url=https://www.ibm.com/ibm/history/exhibits/mainframe/mainframe_PP1620.html |access-date=2022-03-06 |website=www.ibm.com |language=en-US}}</ref> One peculiar feature of the machine is that it lacks any arithmetic circuitry.<ref>{{Cite journal |last=Sweeney |first=D.

|||

Both of these systems run [[Fortran]] and other languages.<ref>{{cite web |date=2019-07-05 |title=IBM 1130 Press Release |url=http://www.ibm1130.net/1130Release.html |access-date=2022-03-06 |archive-url=https://web.archive.org/web/20190705200515/http://www.ibm1130.net/1130Release.html |archive-date=2019-07-05 }}</ref> They are built into roughly desk-sized cabinets, with console typewriters. They have optional add-on disk drives, printers, and both paper-tape and punched-card I/O. |
|||
The more widespread adoption of these technologies into mainstream PCs was a direct factor in the decline of the workstation as a separate market segment: |
|||
*High performance [[Central processing unit|CPUs]]: while RISC in its early days (early 1980s) offered something like an order-of-magnitude performance improvement over [[Complex instruction set computer|CISC]] processors of comparable cost, one particular family of CISC processors, [[Intel]]'s [[x86]], always had the edge in market share and the [[economies of scale]] that this implied. By the mid-1990s, some x86 CPUs had achieved performance on a parity with RISC in some areas, such as integer performance (albeit at a cost of greater chip complexity), relegating the latter to even more high-end markets for the most part. |
|||
*Hardware support for [[floating-point]] operations: optional on the original IBM PC; remained on a separate chip for Intel systems until the [[80486DX]] processor. Even then, x86 floating-point performance continued to lag behind other processors due to limitations in its architecture. Today even low-price PCs now have performance in the gigaFLOPS range, but higher-end systems are preferred for floating-point intensive tasks. |
|||
*Large memory configurations: PCs (i.e. IBM-compatibles) were originally limited to a 640 KB memory capacity (not counting bank-switched "expanded memory") until the 1982 introduction of the [[80286]] processor; early workstations provided access to several megabytes of memory. Even after PCs broke the 640 KB limit with the 80286, special programming techniques were required to address significant amounts of memory until the 80386, as opposed to other 32-bit processors such as [[SPARC]] which provided straightforward access to nearly their entire 4 GB memory address range. 64-bit workstations and servers supporting an address range far beyond 4 GB have been available since the early 1990s, a technology just beginning to appear in the PC desktop and server market in the mid-2000s. |
|||
*[[Operating system]]: early workstations ran the [[Unix]] operating system (OS) or a [[Unix-like]] variant or equivalent such as [[OpenVMS|VMS]]. The PC CPUs of the time had limitations in memory capacity and [[protected mode|memory access protection]], making them unsuitable to run OSes of this sophistication, but this, too, began to change in the late 1980s as PCs with the [[32-bit]] [[80386]] with integrated paged [[Memory management unit|MMUs]] became widely affordable. |
|||
*High-speed [[computer network|networking]] (10 Mbit/s or better): 10 Mbit/s network interfaces were commonly available for PCs by the early 1990s, although by that time workstations were pursuing even higher networking speeds, moving to 100 Mbit/s, 1 Gbit/s, and 10 Gbit/s. However, economies of scale and the demand for high speed networking in even non-technical areas has dramatically decreased the time it takes for newer networking technologies to reach commodity price points. |
|||
*Large displays (17" to 21"), high resolutions, high refresh rate were common among PCs by the late 1990s, although in the late 1980s and early 1990s, this was rare. |
|||
*High-performance [[3D computer graphics|3D graphics]] hardware: this started to become increasingly popular in the PC market around the mid-to-late 1990s, mostly driven by computer gaming, although workstations featured better quality, sometimes sacrificing performance. |
|||
*High performance/high capacity data storage: early workstations tended to use proprietary disk interfaces until the emergence of the SCSI standard in the mid-1980s. Although SCSI interfaces soon became available for PCs, they were comparatively expensive and tended to be limited by the speed of the PC's [[Industry Standard Architecture|ISA]] peripheral bus (although SCSI did become standard on the [[Apple Macintosh]]). SCSI is an advanced controller interface which is particularly good where the disk has to cope with multiple requests at once. This makes it suited for use in servers, but its benefits to desktop PCs which mostly run single-user operating systems are less clear. These days, with desktop systems acquiring more multi-user capabilities (and the increasing popularity of [[Linux]]), the new disk interface of choice is [[Serial ATA]], which has throughput comparable to SCSI but at a lower cost. |
|||
*Extremely reliable components: together with multiple CPUs with greater cache and error correcting memory, this may remain the distinguishing feature of a workstation today. Although most technologies implemented in modern workstations are also available at lower cost for the consumer market, finding good components and making sure they work compatibly with each other is a great challenge in workstation building. Because workstations are designed for high-end tasks such as weather forecasting, video rendering, and game design, it's taken for granted that these systems must be running under full-load, non-stop for several hours or even days without issue. Any off-the-shelf components can be used to build a workstation, but the lifespans of such components under such rigorous conditions are questionable. For this reason, almost no workstations are built by the customer themselves but rather purchased from a vendor such as [[Hewlett-Packard]], [[IBM]], [[Sun Microsystems]], [[Silicon Graphics|SGI]] or [[Dell, Inc.|Dell]]. |
|||
*Tight integration between the OS and the hardware: Workstation vendors both design the hardware and maintain the Unix operating system variant that runs on it. This allows for much more rigorous testing than is possible with an operating system such as Windows. Windows requires that 3rd party hardware vendors write compliant hardware drivers that are stable and reliable. Also, minor variation in hardware quality such as timing or build quality can affect the reliability of the overall machine. Workstation vendors are able to ensure both the quality of the hardware, and the stability of the operating system drivers by validating these things in-house, and this leads to a generally much more reliable and stable machine. |
|||
Early workstations were generally dedicated [[minicomputer]]s, a multiuser system reserved for one user.{{r|baran198902}} For example, the [[PDP-8]] from [[Digital Equipment Corporation]], is regarded as the first commercial minicomputer.<ref>{{Cite book |last=Hey |first=Anthony J. G. |title=The computing universe : a journey through a revolution |date=2015 |others=Gyuri Pápay |publisher=Cambridge University Press |isbn=978-1-316-12976-0 |oclc=899007268}}</ref> |
|||
These days, workstations have changed greatly. Since many of the components are now the same as those used in the consumer market, the price differential between the lower end workstation and consumer PCs may be narrower than it once was. For example, some low-end workstations use CISC based processors like the [[Intel]] [[Pentium 4]] or [[AMD]] [[Athlon 64]] as their CPUs. Higher-end workstations still use more sophisticated CPUs such as the Intel [[Xeon]], AMD [[Opteron]], [[IBM POWER]], or Sun's [[UltraSPARC]], and run a variant of [[Unix]], delivering a truly reliable workhorse for computing-intensive tasks. |
|||
Workstations have historically been more advanced than contemporary PCs, with more powerful CPU architectures, earlier networking, more advanced graphics, more memory, and multitasking with sophisticated operating systems like Unix. Because of their minicomputer heritage, from the start workstations have run professional and expensive software such as CAD and graphics design, as opposed to PCs' games and text editors.{{r|baran198902}} The [[Lisp machine]]s developed at [[Massachusetts Institute of Technology|MIT]] in the early 1970s pioneered some workstation principles, as high-performance, networked, single-user systems intended for heavily interactive use. Lisp Machines were commercialized beginning 1980 by companies like [[Symbolics]], [[Lisp Machines]], [[Texas Instruments]] (the [[TI Explorer]]), and [[Xerox]] (the [[Interlisp-D]] workstations). The first computer designed for a single user, with high-resolution graphics (and so a workstation in the modern sense), is the [[Xerox Alto|Alto]] developed at [[Xerox PARC]] in 1973.<ref>{{Cite book |last=Newquist |first=HP |url=http://archive.org/details/brainmakers0000newq |title=The Brain Makers |date=1994 |publisher=Indianapolis, Ind. : Sams Pub. |others=Internet Archive |isbn=978-0-672-30412-5}}</ref> Other early workstations include the [[Terak 8510/a]] (1977),<ref>{{cite web |title=» Pascal and the P-Machine The Digital Antiquarian |url=https://www.filfre.net/2012/03/pascal-and-the-p-machine/ |access-date=2022-03-08 |language=en-US}}</ref> [[Three Rivers PERQ]] (1979), and the later [[Xerox Star]] (1981). |
|||
Indeed, it is perhaps in the area of the more sophisticated CPU where the true workstation may be found. Although both the consumer desktop and the workstation benefit from CPUs designed around the multicore concept (essentially, multiple processors on a die, of which the POWER4 was a pioneer of this technique), modern (as of 2008) workstations use multiple multicore CPUs, error correcting memory and much larger on-die caches. Such power and reliability are not normally required on a general desktop computer. IBM's POWER-based processor boards and the workstation-level Intel-based Xeon processor boards, for example, have multiple CPUs, more on-die cache and EEC memory, which are features more suited to demanding content-creation, engineering and scientific work than to general desktop computing. |
|||
===1980s rise in popularity=== |
|||
Some workstations are designed for use with only one specific application such as [[AutoCAD]], [[Avid]] [[Xpress Studio HD]], [[3D Studio Max]], etc. To ensure compatibility with the software, purchasers usually ask for a certificate from the software vendor. The certification process makes the workstation's price jump several notches but for professional purposes, reliability is more important than the cost. |

In the early 1980s, with the advent of [[32-bit]] [[microprocessor]]s such as the [[Motorola 68000]], several new competitors appeared, including [[Apollo Computer]] and [[Sun Microsystems]],<ref>{{cite web |date=2013-02-11 |title=The Death Of The Workstation? - INFOtainment News |url=https://infotainmentnews.net/the-death-of-the-workstation/ |access-date=2022-03-19 |language=en-US}}</ref> with workstations based on 68000 and [[Unix]].<ref>{{cite web |title=The SUN workstation architecture |url=http://i.stanford.edu/pub/cstr/reports/csl/tr/82/229/CSL-TR-82-229.pdf |access-date=15 March 2022 |website=Stanford University}}</ref><ref>{{cite web |title=Apollo Domain DN100 workstation - CHM Revolution |url=https://www.computerhistory.org/revolution/computer-graphics-music-and-art/15/217/605 |access-date=2022-03-10 |website=www.computer history.org}}</ref> Meanwhile, [[DARPA]]'s [[VLSI Project]] created several spinoff graphics products, such as the [[Silicon Graphics]] [[Silicon Graphics#IRIS 2000 and 3000 series|3130]].

By then a {{US$|long=no|12000|1989|about|round=-3}} "personal workstation" might be a high-end PC like [[Macintosh II]] or [[IBM PS/2 Model 80]], low-end workstation, or a hybrid device like the [[NeXT Computer]], all with similar, overlapping specifications.{{r|baran198902}} One differentiator between PC and workstation was that the latter was much more likely to have a [[graphics accelerator]] with support for a graphics standard like [[PHIGS]] or [[X Window]], while the former usually depended on [[software rendering]] or proprietary accelerators. The [[computer animation]] industry's needs typically caused improvements in graphical technology, with CAD using the same improvements later.{{r|robinson198902}} ''BYTE'' predicted in 1989 "Soon, the only way we'll be able to tell the difference between traditional workstations and PCs will be by the operating system they run", with the former running Unix and the latter running [[OS/2]], [[classic Mac OS]], and/or Unix. Many workstations by then had some method to run increasingly popular and powerful PC software such as [[Lotus 1-2-3]] or [[Microsoft Word]].{{r|baran198902}} The magazine demonstrated that year that an individual could build a workstation with commodity components with specifications comparable to commercially available low-end workstations.<ref name="nicholls198902">{{Cite magazine |last=Nicholls |first=Bill |date=February 1989 |title=The Current Crop |url=https://archive.org/details/eu_BYTE-1989-02_OCR/page/n290/mode/1up?view=theater |access-date=2024-10-08 |magazine=BYTE |pages=235-244}}</ref> |

Perhaps the first computer that might qualify as a "workstation" was the [[IBM 1620]], a small scientific computer designed to be used interactively by a single person sitting at the console. It was introduced in 1959. One peculiar feature of the machine was that it lacked any actual arithmetic circuitry. To perform addition, it required a memory-resident table of decimal addition rules. This saved on the cost of logic circuitry, enabling IBM to make it inexpensive. The machine was code-named CADET, which some people waggishly claimed meant "Can't Add, Doesn't Even Try". Nonetheless, it rented initially for $1000 a month. |
|||
Workstations often featured [[SCSI]] or [[Fibre Channel]] disk storage systems, high-end [[3D accelerator]]s, single or multiple [[64-bit]] [[central processing unit|processors]],<ref>{{Cite book |url=https://books.google.com/books?id=RJ1OAAAAIBAJ&dq=%22Workstation%22&pg=PA45&article_id=5472,2450145 |title=New Straits Times |publisher=New Straits Times |language=en}}</ref> large amounts of [[Random-access memory|RAM]], and well-designed cooling. Additionally, the companies that make the products tend to have comprehensive repair/replacement plans. As the distinction between workstation and PC fades, however, workstation manufacturers have increasingly employed "off-the-shelf" PC components and graphics solutions rather than proprietary hardware or software. Some "low-cost" workstations are still expensive by PC standards but offer binary compatibility with higher-end workstations and servers made by the same vendor. This allows software development to take place on low-cost (relative to the server) desktop machines. |
|||
In 1965, IBM introduced the [[IBM 1130]] scientific computer, which was meant as the successor to the 1620. Both of these systems came with the ability to run programs written in [[Fortran]] and other languages. Both the 1620 and the 1130 were built into roughly desk-sized cabinets. Both were available with add-on disk drives, printers, and both paper-tape and punched-card I/O. A console typewriter for direct interaction was standard on each. |
|||
===Thin clients=== |
|||
Early examples of workstations were generally dedicated [[minicomputer]]s; a system designed to support a number of users would instead be reserved exclusively for one person. A notable example was the [[PDP-8]] from [[Digital Equipment Corporation]], regarded to be the first commercial minicomputer. |
|||
Workstations diversified to the lowest possible price point as opposed to performance, called the [[thin client]] or [[network computer]]. Dependent upon a network and server, this reduces the machine to having no hard drive, and only the CPU, keyboard, mouse, and screen. Some [[diskless node]]s still run a traditional operating system and perform computations locally, with storage on a remote [[Server (computing)|server]].<ref>{{Cite book |last1=Conrad |first1=Eric |date=2012 |url=http://dx.doi.org/10.1016/b978-1-59749-961-3.00003-0 |title=CISSP Study Guide |pages=63–141 |publisher=Elsevier |access-date=2022-03-18 |last2=Misenar |first2=Seth |last3=Feldman |first3=Joshua|doi=10.1016/b978-1-59749-961-3.00003-0 |isbn=9781597499613 }}</ref> These are intended to reduce the initial system purchase cost, and the [[total cost of ownership]], by reducing the amount of administration required per user.<ref>{{cite web |title=Diskless Nodes HOW-TO document for Linux: What is this all about? |url=http://www.ossh.com/howto/Diskless-HOWTO-1.html |access-date=2022-03-18 |website=www.ossh.com}}</ref> |

This approach was first attempted as a replacement for PCs in office productivity applications, with the [[3Station]] by [[3Com]]. In the 1990s, [[X terminal]]s filled a similar role for technical computing. Sun's [[thin client]]s include the [[Sun Ray]] product line.<ref>{{cite news |title=CNN - Here comes the Sun Ray - November 2, 1999 |url=http://www.cnn.com/TECH/computing/9911/02/sun.ray.idg/ |access-date=2022-03-18 |website=www.CNN.com}}</ref> However, traditional workstations and PCs continued to drop in price and complexity as remote management tools for IT staff became available, undercutting this market. |
|||
The [[Lisp machine]]s developed at [[Massachusetts Institute of Technology|MIT]] in the early 1970s pioneered some of the principles of the workstation computer, as they were high-performance, single-user systems intended for heavily interactive use. The first computer designed for single-users, with high-resolution graphics facilities (and so a workstation in the modern sense of the term) was the [[Xerox Alto]] developed at [[Xerox PARC]] in 1973. Other early workstations include the [[Three Rivers PERQ]] (1979) and the later [[Xerox Star]] (1981). |
|||
===3M computer=== |
|||
In the early 1980s, with the advent of [[32-bit]] [[microprocessor]]s such as the [[Motorola 68000]], a number of new participants in this field appeared, including [[Apollo Computer]] and [[Sun Microsystems]], who created [[Unix]]-based workstations based on this processor. Meanwhile [[DARPA]]'s [[VLSI Project]] created several spinoff graphics products as well, notably the [[SGI 3130]], and [[Silicon Graphics]]' range of machines that followed. It was not uncommon to differentiate the target market for the products, with Sun and Apollo considered to be '''network workstations''', while the SGI machines were '''graphics workstations'''. As [[RISC]] microprocessors became available in the mid-1980s, these were adopted by many workstation vendors. |

A high-end workstation of the early 1980s with the three Ms, or a "3M computer" (coined by Raj Reddy and his colleagues at CMU), has one megabyte of RAM, a megapixel display (roughly 1000×1000 pixels), and one "[[megaflop|MegaFLOPS]]" compute performance (at least one million floating-point operations per second).<ref>Andries van Dam; David H. Laidlaw; Rosemary Michelle Simpson (2002-08-04). "Experiments in Immersive Virtual Reality for Scientific Visualization". Computers & Graphics. 26 (4): 535–555. CiteSeerX 10.1.1.4.9249. doi:10.1016/S0097-8493(02)00113-9</ref> RFC 782 defines the workstation environment more generally as "hardware and software dedicated to serve a single user", and that it provisions additional shared resources. This is at least one order of magnitude beyond the capacity of the personal computer of the time. The original 1981 [[IBM Personal Computer]] has 16 KB memory, a text-only display, and floating-point performance around {{val|1 |ul=kFLOPS}} ({{val|30 |u=kFLOPS}} with the optional 8087 math coprocessor. Other features beyond the typical personal computer include networking, graphics acceleration, and high-speed internal and peripheral data buses. |
|||
Another goal was to bring the price below one "[[wikt:megapenny|megapenny]]", that is, less than {{US$|long=no|10000|1985|about|round=-3}}, which was achieved in the late 1980s. Throughout the early to mid-1990s, many workstations cost from {{US$|15000|long=no}} to {{USD|100000|long=no|1995|round=-3}} or more. |
|||
Workstations tended to be very expensive, typically several times the cost of a standard PC and sometimes costing as much as a new [[automobile|car]]. However, minicomputers sometimes cost as much as a house. The high expense usually came from using costlier components that ran faster than those found at the local computer store, as well as the inclusion of features not found in PCs of the time, such as high-speed networking and sophisticated graphics. Workstation manufacturers also tend to take a "balanced" approach to system design, making certain to avoid bottlenecks so that data can flow unimpeded between the many different subsystems within a computer. Additionally, workstations, given their more specialized nature, tend to have higher [[profit margin]]s than [[commodity]]-driven PCs. |
|||
===Decline=== |
|||
The systems that come out of workstation companies often feature [[SCSI]] or [[Fibre Channel]] disk storage systems, high-end [[3D accelerator]]s, single or multiple [[64-bit]] [[central processing unit|processors]], large amounts of [[random access memory|RAM]], and well-designed cooling. Additionally, the companies that make the products tend to have very good repair/replacement plans. However, the line between workstation and PC is increasingly becoming blurred as the demand for fast computers, networking and graphics have become common in the consumer world, allowing workstation manufacturers to use "off the shelf" PC components and graphics solutions as opposed to [[Proprietary software|proprietary]] in-house developed technology. Some "low-cost" workstations are still expensive by PC standards, but offer binary compatibility with higher-end workstations and servers made by the same vendor. This allows software development to take place on low-cost (relative to the server) desktop machines. |
|||
The more widespread adoption of these technologies into mainstream PCs was a direct factor in the decline of the workstation as a separate market segment:<ref>{{Cite book |url=https://books.google.com/books?id=XGlGAAAAIBAJ&dq=%22Workstation%22&pg=PA14&article_id=6267,1290833 |title=The Daily Gazette |publisher=The Daily Gazette |language=en}}</ref> |
|||
* Reliable components |
|||
There have been several attempts to produce a workstation-like machine specifically for the lowest possible price point as opposed to performance. One approach is to remove local storage and reduce the machine to the processor, keyboard, mouse and screen. In some cases, these ''[[diskless node]]s'' would still run a traditional OS and perform computations locally, with storage on a remote [[Server (computing)|server]]. These approaches are intended not just to reduce the initial system purchase cost, but lower the [[total cost of ownership]] by reducing the amount of administration required per user. |
|||
* High-performance [[3D computer graphics|3D graphics]] hardware for [[computer-aided design ]] (CAD) and [[computer-generated imagery]] (CGI) animation is increasingly popular in the PC market around the mid-to-late 1990s mostly driven by computer gaming, yielding the first official GPU in [[Nvidia]]'s NV10 and the breakthrough [[GeForce 256]]. |
|||
* High-performance [[Central processing unit|CPUs]]: the first [[Reduced instruction set computing|RISC]] of the early 1980s offer roughly one order of magnitude in performance improvement over [[Complex instruction set computer|CISC]] processors of comparable cost. [[Intel]]'s [[x86]] CISC family always had the edge in market share and the [[economies of scale]] that this implied. By the mid-1990s, some CISC processors like the [[Motorola 68040]] and Intel's [[i486|80486]] and [[Pentium (original)|Pentium]] have performance parity with RISC in some areas, such as integer performance (at the cost of greater chip complexity) and hardware [[floating-point]] calculations, relegating RISC to even more high-end markets.<ref name=macworld>{{cite magazine |

|||
* Hardware support for [[floating-point]] operations: optional on the original IBM PC; remained on a separate chip for Intel systems until the [[80486DX]] processor. Even then, x86 floating-point performance lags other processors due to limitations in its architecture. Today even low-price PCs now have performance in the gigaFLOPS range. |
|||
* High-performance/high-capacity data storage: early workstations tend to use proprietary disk interfaces until the SCSI standard of the mid-1980s. Although SCSI interfaces soon became available for IBM PCs, they were comparatively expensive and tend to be limited by the speed of the PC's [[Industry Standard Architecture|ISA]] peripheral bus. SCSI is an advanced controller interface good for multitasking and daisy chaining. This makes it suited for use in servers, and its benefits to desktop PCs which mostly run single-user operating systems are less clear, but it is standard on the 1980s-1990s Macintosh. [[Serial ATA]] is more modern, with throughput comparable to SCSI but at a lower cost. |
|||
* High-speed [[computer network|networking]] (10 Mbit/s or better): 10 Mbit/s network interfaces were commonly available for PCs by the early 1990s, although by that time workstations were pursuing even higher networking speeds, moving to 100 Mbit/s, 1 Gbit/s, and 10 Gbit/s. However, economies of scale and the demand for high-speed networking in even non-technical areas have dramatically decreased the time it takes for newer networking technologies to reach commodity price points. |
|||
* Large displays (17- to 21-inch) with high resolutions and high refresh rates for graphics and CAD work, which were rare among PCs in the late 1980s and early 1990s but became common among PCs by the late 1990s. |
|||
* Large memory configurations: PCs (such as IBM clones) are originally limited to 640 KB of RAM until the 1982 introduction of the [[80286]] processor; early workstations have megabytes of memory. IBM clones require special programming techniques to address more than 640 KB until the 80386, as opposed to other 32-bit processors such as [[SPARC]] which provide straightforward access to nearly their entire 4 GB memory address range. 64-bit workstations and servers supporting an address range far beyond 4 GB have been available since the early 1990s, a technology just beginning to appear in the PC desktop and server market in the mid-2000s. |
|||
* [[Operating system]]: early workstations ran the [[Unix]] operating system (OS), a [[Unix-like]] variant, or an unrelated equivalent OS such as [[OpenVMS|VMS]]. The PC CPUs of the time have limitations in memory capacity and [[protected mode|memory access protection]], making them unsuitable to run OSes of this sophistication, but this, too, began to change in the late 1980s as PCs with the [[32-bit]] [[80386]] with integrated paged [[Memory management unit|MMUs]] became widely affordable and enabling [[OS/2]], [[Windows NT 3.1]], and Unix-like systems based on [[BSD]] and [[Linux]] on commodity PC hardware. |
|||
* Tight integration between the OS and the hardware: Workstation vendors both design the hardware and maintain the Unix operating system variant that runs on it. This allows for much more rigorous testing than is possible with an operating system such as Windows. Windows requires that third-party hardware vendors write compliant hardware drivers that are stable and reliable. Also, minor variations in hardware quality such as timing or build quality can affect the reliability of the overall machine. Workstation vendors are able to ensure both the quality of the hardware, and the stability of the operating system drivers by validating these things in-house, and this leads to a generally much more reliable and stable machine. |
|||
===Market position=== |
|||
This approach was actually first attempted as a replacement for PCs in office productivity applications, with the [[3Station]] by [[3Com]] as an early example; in the 1990s, [[X terminal]]s filled a similar role for technical computing. Sun has also introduced "[[thin client]]s", most notably its [[Sun Ray]] product line. However, traditional workstations and PCs continue to drop in price, which tends to undercut the market for products of this type. |
|||
[[File:Sun Ultra 20 Workstation (2005).jpeg|thumb|[[Sun Ultra series|Sun Ultra 20]] with [[AMD]] [[Opteron]] processor and [[Solaris (operating system)|Solaris 10]]]] |
|||
Since the late 1990s, the workstation and consumer markets have further merged. Many low-end workstation components are now the same as the consumer market, and the price differential narrowed. For example, most [[Macintosh Quadra]] computers were originally intended for scientific or design work, all with the [[Motorola 68040]] CPU, backward compatible with [[Motorola 68000 series|68000]] Macintoshes. The consumer [[Macintosh IIcx]] and [[Macintosh IIci]] models can be upgraded to the [[Quadra 700]]. "In an era when many professionals preferred Silicon Graphics workstations, the Quadra 700 was an intriguing option at a fraction of the cost" as resource-intensive software such as [[Infini-D]] brought "studio-quality 3D rendering and animations to the home desktop". The Quadra 700 can run [[A/UX]] 3.0, making it a [[Unix]] workstation.<ref>{{cite web|date=11 December 2020|first=Chris|last=Wilkinson|title=Working from home at 25MHz: You could do worse than a Quadra 700 (even in 2020)|url=https://arstechnica.com/information-technology/2020/12/it-still-runs-on-your-imagination-passing-2020-time-with-a-macintosh-quadra-700/|work=Ars Technica}}</ref> Another example is the [[Nvidia]] [[GeForce 256]] consumer graphics card, which spawned the [[Nvidia Quadro|Quadro]] workstation card, which has the same GPU but different driver support and certifications for CAD applications and a much higher price. |
|||
Workstations have typically driven advancements in CPU technology. All computers benefit from multi-processor and multicore designs (essentially, multiple processors on a [[die (integrated circuit)|die]]). The multicore design was pioneered by IBM's [[POWER4]]; it and Intel Xeon have multiple CPUs, more on-die cache, and ECC memory. |
|||
===Workstation class PCs=== |
|||
A significant segment of the desktop market are computers expected to perform as workstations, but using PC operating systems and components. PC component manufacturers will often segment their product line, and market premium components which are functionally similar to the cheaper "consumer" models but feature a higher level of robustness and/or performance. Notable examples of this are the [[AMD]] [[Opteron]], [[Intel Corporation|Intel]] [[Xeon]] processors, and the [[ATI FireGL]] and [[Nvidia Quadro]] graphics processors. |
|||
Some workstations are designed or certified for use with only one specific application such as [[AutoCAD]], [[Avid Technology|Avid]] Xpress Studio HD, or [[3D Studio Max]]. The certification process increases workstation prices. |
|||
A workstation class PC may have some of the following features: |
|||
* support for ECC memory |
|||
* a larger number of memory sockets which use registered (buffered) modules |
|||
* multiple processors |
|||
* multiple displays |
|||
* run a "business" or "professional" operating system version |

A workstation is a special computer designed for technical or scientific applications.[2] Intended primarily to be used by a single user,[2] they are commonly connected to a local area network and run multi-user operating systems. The term workstation has been used loosely to refer to everything from a mainframe computer terminal to a PC connected to a network, but the most common form refers to the class of hardware offered by several current and defunct companies such as Sun Microsystems,[3] Silicon Graphics, Apollo Computer,[4] DEC, HP, NeXT, and IBM which powered the 3D computer graphics revolution of the late 1990s.[5]
Workstations formerly offered higher performance than mainstream personal computers, especially in CPU, graphics, memory, and multitasking. Workstations are optimized for the visualization and manipulation of different types of complex data such as 3D mechanical design, engineering simulations like computational fluid dynamics, animation, video editing, image editing, medical imaging, image rendering, computational science, generating mathematical plots, and software development. Typically, the form factor is that of a desktop computer, which consists of a high-resolution display, a keyboard, and a mouse at a minimum, but also offers multiple displays, graphics tablets, and 3D mice for manipulating objects and navigating scenes. Workstations were the first segment of the computer market[6] to present advanced accessories, and collaboration tools like videoconferencing.[5]
The increasing capabilities of mainstream PCs since the late 1990s have reduced distinction between the PCs and workstations.[7] Typical 1980s workstations have expensive proprietary hardware and operating systems to categorically distinguish from standardized PCs. From the 1990s and 2000s, IBM's RS/6000 and IntelliStation have RISC-based POWER CPUs running AIX, and its IBM PC Series and Aptiva corporate and consumer PCs have Intel x86 CPUs. However, by the early 2000s, this difference largely disappeared, since workstations use highly commoditized hardware dominated by large PC vendors, such as Dell, Hewlett-Packard, and Fujitsu, selling x86-64 systems running Windows or Linux.
History
[edit]Origins and development
[edit]Workstations are older than the first personal computer (PC).[8] The first computer that might qualify as a workstation is the IBM 1620, a small scientific computer designed to be used interactively by a single person sitting at the console.[9] It was introduced in 1959.[10] One peculiar feature of the machine is that it lacks any arithmetic circuitry.[11] To perform addition, it requires a memory-resident table of decimal addition rules.[12] This reduced the cost of logic circuitry, enabling IBM to make it inexpensive. The machine is codenamed CADET and was initially rented for $1000 per month.
In 1965, the IBM 1130 scientific computer became the successor to 1620. Both of these systems run Fortran and other languages.[13] They are built into roughly desk-sized cabinets, with console typewriters. They have optional add-on disk drives, printers, and both paper-tape and punched-card I/O.
Early workstations were generally dedicated minicomputers, a multiuser system reserved for one user.[8] For example, the PDP-8 from Digital Equipment Corporation, is regarded as the first commercial minicomputer.[14]
Workstations have historically been more advanced than contemporary PCs, with more powerful CPU architectures, earlier networking, more advanced graphics, more memory, and multitasking with sophisticated operating systems like Unix. Because of their minicomputer heritage, from the start workstations have run professional and expensive software such as CAD and graphics design, as opposed to PCs' games and text editors.[8] The Lisp machines developed at MIT in the early 1970s pioneered some workstation principles, as high-performance, networked, single-user systems intended for heavily interactive use. Lisp Machines were commercialized beginning 1980 by companies like Symbolics, Lisp Machines, Texas Instruments (the TI Explorer), and Xerox (the Interlisp-D workstations). The first computer designed for a single user, with high-resolution graphics (and so a workstation in the modern sense), is the Alto developed at Xerox PARC in 1973.[15] Other early workstations include the Terak 8510/a (1977),[16] Three Rivers PERQ (1979), and the later Xerox Star (1981).
1980s rise in popularity
[edit]In the early 1980s, with the advent of 32-bit microprocessors such as the Motorola 68000, several new competitors appeared, including Apollo Computer and Sun Microsystems,[17] with workstations based on 68000 and Unix.[18][19] Meanwhile, DARPA's VLSI Project created several spinoff graphics products, such as the Silicon Graphics 3130. Target markets were differentiated, with Sun and Apollo considered to be network workstations and SGI as graphics workstations. RISC CPUs increased in the mid-1980s, typical of workstation vendors.[20] Competition between RISC vendors lowered CPU prices to as little as $10 per MIPS, much less expensive than the Intel 80386;[21] after large price cuts in 1987 and 1988, a personal workstation suitable for 2D CAD costing $5,000 (equivalent to $12,000 in 2023) to $25,000 (equivalent to $61,000 in 2023) was available from multiple vendors. Mid-range models capable of 3D graphics cost from $35,000 (equivalent to $86,000 in 2023) to $60,000 (equivalent to $147,000 in 2023), while high-end models overlapping with minicomputers cost from $80,000 (equivalent to $197,000 in 2023) to $100,000 (equivalent to $246,000 in 2023) or more.[22]
By then a $12,000 (equivalent to $29,000 in 2023) "personal workstation" might be a high-end PC like Macintosh II or IBM PS/2 Model 80, low-end workstation, or a hybrid device like the NeXT Computer, all with similar, overlapping specifications.[8] One differentiator between PC and workstation was that the latter was much more likely to have a graphics accelerator with support for a graphics standard like PHIGS or X Window, while the former usually depended on software rendering or proprietary accelerators. The computer animation industry's needs typically caused improvements in graphical technology, with CAD using the same improvements later.[22] BYTE predicted in 1989 "Soon, the only way we'll be able to tell the difference between traditional workstations and PCs will be by the operating system they run", with the former running Unix and the latter running OS/2, classic Mac OS, and/or Unix. Many workstations by then had some method to run increasingly popular and powerful PC software such as Lotus 1-2-3 or Microsoft Word.[8] The magazine demonstrated that year that an individual could build a workstation with commodity components with specifications comparable to commercially available low-end workstations.[23]
Workstations often featured SCSI or Fibre Channel disk storage systems, high-end 3D accelerators, single or multiple 64-bit processors,[24] large amounts of RAM, and well-designed cooling. Additionally, the companies that make the products tend to have comprehensive repair/replacement plans. As the distinction between workstation and PC fades, however, workstation manufacturers have increasingly employed "off-the-shelf" PC components and graphics solutions rather than proprietary hardware or software. Some "low-cost" workstations are still expensive by PC standards but offer binary compatibility with higher-end workstations and servers made by the same vendor. This allows software development to take place on low-cost (relative to the server) desktop machines.
Thin clients
[edit]Workstations diversified to the lowest possible price point as opposed to performance, called the thin client or network computer. Dependent upon a network and server, this reduces the machine to having no hard drive, and only the CPU, keyboard, mouse, and screen. Some diskless nodes still run a traditional operating system and perform computations locally, with storage on a remote server.[25] These are intended to reduce the initial system purchase cost, and the total cost of ownership, by reducing the amount of administration required per user.[26]
This approach was first attempted as a replacement for PCs in office productivity applications, with the 3Station by 3Com. In the 1990s, X terminals filled a similar role for technical computing. Sun's thin clients include the Sun Ray product line.[27] However, traditional workstations and PCs continued to drop in price and complexity as remote management tools for IT staff became available, undercutting this market.
3M computer
[edit]A high-end workstation of the early 1980s with the three Ms, or a "3M computer" (coined by Raj Reddy and his colleagues at CMU), has one megabyte of RAM, a megapixel display (roughly 1000×1000 pixels), and one "MegaFLOPS" compute performance (at least one million floating-point operations per second).[28] RFC 782 defines the workstation environment more generally as "hardware and software dedicated to serve a single user", and that it provisions additional shared resources. This is at least one order of magnitude beyond the capacity of the personal computer of the time. The original 1981 IBM Personal Computer has 16 KB memory, a text-only display, and floating-point performance around 1 kFLOPS (30 kFLOPS with the optional 8087 math coprocessor. Other features beyond the typical personal computer include networking, graphics acceleration, and high-speed internal and peripheral data buses.
Another goal was to bring the price below one "megapenny", that is, less than $10,000 (equivalent to $28,000 in 2023), which was achieved in the late 1980s. Throughout the early to mid-1990s, many workstations cost from $15,000 to $100,000 (equivalent to $200,000 in 2023) or more.
Decline
[edit]The more widespread adoption of these technologies into mainstream PCs was a direct factor in the decline of the workstation as a separate market segment:[29]
- Reliable components
- High-performance 3D graphics hardware for computer-aided design (CAD) and computer-generated imagery (CGI) animation is increasingly popular in the PC market around the mid-to-late 1990s mostly driven by computer gaming, yielding the first official GPU in Nvidia's NV10 and the breakthrough GeForce 256.
- High-performance CPUs: the first RISC of the early 1980s offer roughly one order of magnitude in performance improvement over CISC processors of comparable cost. Intel's x86 CISC family always had the edge in market share and the economies of scale that this implied. By the mid-1990s, some CISC processors like the Motorola 68040 and Intel's 80486 and Pentium have performance parity with RISC in some areas, such as integer performance (at the cost of greater chip complexity) and hardware floating-point calculations, relegating RISC to even more high-end markets.[30]
- Hardware support for floating-point operations: optional on the original IBM PC; remained on a separate chip for Intel systems until the 80486DX processor. Even then, x86 floating-point performance lags other processors due to limitations in its architecture. Today even low-price PCs now have performance in the gigaFLOPS range.
- High-performance/high-capacity data storage: early workstations tend to use proprietary disk interfaces until the SCSI standard of the mid-1980s. Although SCSI interfaces soon became available for IBM PCs, they were comparatively expensive and tend to be limited by the speed of the PC's ISA peripheral bus. SCSI is an advanced controller interface good for multitasking and daisy chaining. This makes it suited for use in servers, and its benefits to desktop PCs which mostly run single-user operating systems are less clear, but it is standard on the 1980s-1990s Macintosh. Serial ATA is more modern, with throughput comparable to SCSI but at a lower cost.
- High-speed networking (10 Mbit/s or better): 10 Mbit/s network interfaces were commonly available for PCs by the early 1990s, although by that time workstations were pursuing even higher networking speeds, moving to 100 Mbit/s, 1 Gbit/s, and 10 Gbit/s. However, economies of scale and the demand for high-speed networking in even non-technical areas have dramatically decreased the time it takes for newer networking technologies to reach commodity price points.
- Large displays (17- to 21-inch) with high resolutions and high refresh rates for graphics and CAD work, which were rare among PCs in the late 1980s and early 1990s but became common among PCs by the late 1990s.
- Large memory configurations: PCs (such as IBM clones) are originally limited to 640 KB of RAM until the 1982 introduction of the 80286 processor; early workstations have megabytes of memory. IBM clones require special programming techniques to address more than 640 KB until the 80386, as opposed to other 32-bit processors such as SPARC which provide straightforward access to nearly their entire 4 GB memory address range. 64-bit workstations and servers supporting an address range far beyond 4 GB have been available since the early 1990s, a technology just beginning to appear in the PC desktop and server market in the mid-2000s.
- Operating system: early workstations ran the Unix operating system (OS), a Unix-like variant, or an unrelated equivalent OS such as VMS. The PC CPUs of the time have limitations in memory capacity and memory access protection, making them unsuitable to run OSes of this sophistication, but this, too, began to change in the late 1980s as PCs with the 32-bit 80386 with integrated paged MMUs became widely affordable and enabling OS/2, Windows NT 3.1, and Unix-like systems based on BSD and Linux on commodity PC hardware.
- Tight integration between the OS and the hardware: Workstation vendors both design the hardware and maintain the Unix operating system variant that runs on it. This allows for much more rigorous testing than is possible with an operating system such as Windows. Windows requires that third-party hardware vendors write compliant hardware drivers that are stable and reliable. Also, minor variations in hardware quality such as timing or build quality can affect the reliability of the overall machine. Workstation vendors are able to ensure both the quality of the hardware, and the stability of the operating system drivers by validating these things in-house, and this leads to a generally much more reliable and stable machine.
Market position
[edit]Since the late 1990s, the workstation and consumer markets have further merged. Many low-end workstation components are now the same as the consumer market, and the price differential narrowed. For example, most Macintosh Quadra computers were originally intended for scientific or design work, all with the Motorola 68040 CPU, backward compatible with 68000 Macintoshes. The consumer Macintosh IIcx and Macintosh IIci models can be upgraded to the Quadra 700. "In an era when many professionals preferred Silicon Graphics workstations, the Quadra 700 was an intriguing option at a fraction of the cost" as resource-intensive software such as Infini-D brought "studio-quality 3D rendering and animations to the home desktop". The Quadra 700 can run A/UX 3.0, making it a Unix workstation.[31] Another example is the Nvidia GeForce 256 consumer graphics card, which spawned the Quadro workstation card, which has the same GPU but different driver support and certifications for CAD applications and a much higher price.
Workstations have typically driven advancements in CPU technology. All computers benefit from multi-processor and multicore designs (essentially, multiple processors on a die). The multicore design was pioneered by IBM's POWER4; it and Intel Xeon have multiple CPUs, more on-die cache, and ECC memory.
Some workstations are designed or certified for use with only one specific application such as AutoCAD, Avid Xpress Studio HD, or 3D Studio Max. The certification process increases workstation prices.
Modern market
[edit]GPU workstations
[edit]Modern workstations are typically desktop computers with AMD or NVIDIA GPUs to do high-performance computing on software programs such as video editing, 3D modeling, computer-aided design, and rendering.[32]
Decline of RISC workstations
[edit]By January 2009, all RISC-based workstation product lines had been discontinued:
- Hewlett-Packard withdrew its last HP 9000 PA-RISC-based desktop products from the market in January 2008.[33]
- IBM retired the IntelliStation POWER on January 2, 2009.[34]
- SGI ended general availability of its MIPS-based SGI Fuel and SGI Tezro workstations in December 2006.[35]
- Sun Microsystems announced end-of-life for its last Sun Ultra SPARC workstations in October 2008.[36]
In early 2018, RISC workstations were reintroduced in a series of IBM POWER9-based systems by Raptor Computing Systems.[37][38] In October of 2024 System 76 introduces The Thelio Astra an Arm workstation aim for autonomous car industry.[39]
x86-64
[edit]Most of the current workstation market uses x86-64 microprocessors. Operating systems include Windows, FreeBSD, Linux distributions, macOS, and Solaris.[40] Some vendors also market commodity mono-socket systems as workstations.
These are three types of workstations:
- Workstation blade systems (IBM HC10 or Hewlett-Packard xw460c. Sun Visualization System is akin to these solutions)[41]
- Ultra high-end workstation (SGI Virtu VS3xx)
- Deskside systems containing server-class CPUs and chipsets on large server-class motherboards with high-end RAM (HP Z-series workstations and Fujitsu CELSIUS workstations)
Definition
[edit]A high-end desktop market segment includes workstations, with PC operating systems and components. Component product lines may be segmented, with premium components that are functionally similar to the consumer models but with higher robustness or performance.[42]
A workstation-class PC may have some of the following features:
- Larger number of memory sockets which use DIMM slots or registered (buffered) modules[43]
- Multiple displays[43]
- Reliable high-performance graphics card[43]
- Multiple processor sockets, powerful CPUs[43]
- Run reliable operating system with advanced features[43]
- Support for ECC memory[43]
- M.2[44] or PCI-E NVMe[45] SSD
