Ryzen (/ˈraɪzɛn/ RYE-zen)[1] is a brand[2] of central processing units (CPUs) and accelerated processing units (APUs) marketed and designed by AMD. The brand was introduced in 2017 with products implementing the Zen microarchitecture.

First Ryzen-branded products were officially announced during AMD's New Horizon summit on December 13, 2016.[3]

History

In the previous 5 years prior to the release of Ryzen, AMD's direct competitor in the x86-64 consumer level CPU marketspace, Intel, had continued to grow it's marketshare with the continued tick-tock cycle of their Intel Core series of chips.[4] Since the release of the Bulldozer in 2011 AMD had fallen behind Intel significantly in both single-core and multi-core CPU performance benchmarks.[citation needed] While AMD had completed a die shrink and revision of the Bulldozer architecture, performance and sales had fallen significantly against the competing Intel products.[citation needed] Ryzen is the first consumer level implementation of the new Zen microarchitecture.[citation needed] With the release of the Ryzen CPU line AMD has offered higher core counts, multi-threaded performance, and improved IPC.[5] However, single threaded performance still lagged Intel, though significantly less than the Bulldozer microarchitecture. Ryzen has also been success in taking back marketshare from Intel.[4]

Summit Ridge

  • All models except Threadripper require AMD Socket AM4.[6][7]
  • All models support DDR4-2666 ×2 Single Rank, DDR4-2400 ×2 Dual Rank, DDR4-2133 ×4 Single Rank, or DDR4-1866 ×4 Dual Rank.[6][8]
  • All models support: x87, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, CLMUL, AVX, AVX2, FMA, CVT16/F16C, ABM, BMI1, BMI2, SHA.[9]
  • Transistors: 4.8 billion[10]
  • Die size: 192 mm² [11]
  • Stepping: B1[12]
  • Ryzen CPUs feature unlocked multipliers across the board for overclocking. All Ryzen products support auto-overclocking, dubbed "XFR" (eXtended Frequency Range), with X branded Ryzen products giving twice the XFR boost as non-X branded Ryzen products (100 MHz overclock vs 50 MHz overclock),[13] although AMD does not list non-X branded Ryzens as having support for XFR.[14]
  • AMD officially revealed their codename "Summit Ridge" Ryzen CPUs on February 22, 2017.[15] Ryzen CPUs differ from Zen-powered APUs in that they exclude an integrated GPU and instead rely on an external, dedicated one.
  • Ryzen is launching in conjunction with a line of stock coolers, the "Wraith Spire", "Wraith Stealth" and "Wraith Max". This line succeeds the original "Wraith" cooler, which was positively received when released in mid-2016.[16] The "Wraith Stealth" and "Wraith Spire" are included with certain Ryzen CPUs, as listed below. the "Stealth" is a low-profile unit meant for the lower-end CPUs and is rated for a TDP of 65W, whereas the "Spire" is the mainstream cooler with a TDP rating of 95W and modest headroom for overclocking, along with optional RGB lighting on certain models. The "Wraith Max" is a larger, aftermarket unit intended to handle more intensive overclocks than the "Spire".
  • All models support AMD's SenseMI Technology, which uses AMD Infinity Control Fabric to offer the following features.[6][17][18]
    • AMD Pure Power reduces the entire ramp of processor voltage and clock speed, for light loads.
    • AMD Precision Boost increases the processor voltage and clock speed while the number of active cores <= 2.
    • AMD XFR (eXtended Frequency Range) increases the processor voltage and clock speed beyond the maximum Precision Boost, when sufficient cooling is available.[19]
    • Neural Net Prediction and Smart Prefetch use true AI inside the processor to optimize instruction workflow and cache management.

Common features of Ryzen 1000 desktop CPUs:

  • Socket: AM4.
  • All the CPUs support DDR4-2666 in dual-channel mode.
  • All the CPUs support 24 PCIe 3.0 lanes. 4 of the lanes are reserved as link to the chipset.
  • No integrated graphics.
  • L1 cache: 96 KB (32 KB data + 64 KB instruction) per core.
  • L2 cache: 512 KB per core.
  • Node/fabrication process: GlobalFoundries 14 LP.

Raven Ridge

AMD's CEO, Lisa Su, confirmed during a March 2017 Reddit AMA on /r/AMD that Zen-based APUs would also be branded Ryzen.[24] Traditionally, AMD's APUs were branded separately from their CPUs. The branding was later clarified as Ryzen Mobile and AMD stated the products would have higher CPU and GPU performance, and lower power, than the previous generation of APUs.[25]

In May 2017, AMD demonstrated a Ryzen Mobile APU with four Zen CPU cores and Vega based GPU.[26]

Compatibility

Although AMD "verified" the ability for computers with Ryzen processors to boot Windows 7 and Windows 10, Microsoft only officially supports Ryzen on computers running Windows 10 per support policies. Windows Update blocks updates from being installed on Ryzen systems running versions older than Windows 10. In support of this position, AMD only provides drivers for Windows 10.[27] Ryzen processors are compatible with Linux; the full performance of Ryzen is enabled in kernel version 4.10 or newer.[28]

Initial reception

The first Ryzen 7 1700, 1700X, and 1800X processors debuted in early March 2017, and were generally well received by hardware reviewers.[29][30][31] Ryzen was the first brand new architecture from AMD in five years, and without very much initial fine-tuning or optimization, it ran generally well for reviewers.[32] Initial Ryzen chips ran well with software and games already on the market, performing exceptionally well in workstation scenarios, and well in most gaming scenarios. Compared to Piledriver-powered FX chips, Zen-powered Ryzen chips ran cooler, much faster, and used less power. IPC uplift was eventually gauged to be 52% higher than Excavator, which was two full generations ahead of the architecture still being used in AMD's FX-series desktop predecessors like the FX-8350 and FX-8370.[33] Power consumption and heat were found to be highly competitive with Intel, and the included Wraith coolers were generally competitive with higher-priced aftermarket solutions.

Ryzen's multi-threaded performance, in some cases while using Blender or other open-source software, was around four times the performance of the FX-8370.[34] One reviewer found that Ryzen chips would typically outperform competing Intel i7 processors for a fraction of the price when all eight cores were utilized.[34]

One complaint among a subset of reviewers, however, was that Ryzen processors fell behind their Intel counterparts when running older games, or running certain newer games at mainstream resolutions such as 720p or 1080p.[35] AMD acknowledged the gaming performance deficit at low resolutions during a Reddit "Ask Me Anything Q & A thread" ,where they explained that updates and patches were being developed.[36] Subsequent updates to Ashes of the Singularity: Escalation and Rise of the Tomb Raider increased frame rates 17−31% on Ryzen systems.[37][38] id Software announced in April 2017 it would be optimizing its future games to make use of the greater parallelism available on Ryzen CPUs.[39]

It has been suggested that low core utilization resulted in Ryzen processors being underutilized, therefore reflecting lower than expected scores, especially when coupled with the fact that Zen's slightly lower IPC relies on full core utilization.[40][41][42] However, AMD and others have argued thread scheduling is not the fundamental issue to Windows 10 performance.[43][44] There were also issues with AM4 motherboards and their BIOS, which was resulting in many Ryzen chips being underclocked, partially shut off, or generally hindered by BIOS bugs.[citation needed]

Known issues

Ryzen faced hard system locks when an application executes certain sequences of FMA3 instructions.[45] AMD stated in mid March 2017 that the issue would be fixed via new microcode included in UEFI updates from motherboard manufacturers.

Some Ryzen processors produce segmentation faults on certain workloads on Linux.[46]
