This is a list of computer motherboard chipsets made by VIA Technologies. Northbridge chips are listed first, primarily by CPU-socket or CPU-family; southbridge chips are listed in a later table.

Background

VIA chipsets support CPUs from Intel, AMD (e.g. the Athlon 64) and VIA themselves (e.g. the VIA C3 or C7). They support CPUs as old as the i386 in the early 1990s. In the early 2000s, their chipsets began to offer on-chip graphics support from VIA's joint venture with S3 Graphics beginning in 2001; this support continued into the early 2010s, with the release of the VX11H in August 2012.

VIA chipsets declined in popularity as other chipsets began to offer better performance, VIA entered other markets and Intel began to offer more powerful integrated graphics on their CPU dies.

Chipsets by CPU socket

The term V-Link indicates VIA's northbridge/southbridge interconnect bus.

The only difference between the Apollo Master and the Apollo Master Plus is that the Plus does not support pipelined burst cache memory.
The Apollo VP and Apollo VP2 chipsets were initially referenced by VIA as Apollo VP-1 and Apollo VP-2 respectively, later renamed to Apollo VP and Apollo VP2 when the "/97" upgrades became available.
The Apollo VPX chipset is a low-cost solution that replaced the Apollo VP but with features similar to the VP2.
AMD licensed the VIA Apollo VP2/97 core logic architecture for its AMD 640 chipset.

ProSavage PM133 - graphics core from S3, derived from a combination of the 3D component of Savage4 and 2D from Savage 2000.
PLE133 and PLE133T - graphics core from Trident, derived from Blade3D.
CLE266 (Castle Rock) - contains a graphics core internally developed by VIA Technologies called UniChrome (codename: Halcyon).
Asus advertised some boards as Apollo Pro 133Z.^[5] 133Z appears to be a late revision of or step up from 133A, but it is not listed on the VIA site.

KT266 contains a hardware bug which causes system instability when using the AGP slot at the specified max capacity of 4×.^[20]
ProSavage KM133, KM133A, KM266, KM400, KM400A - Similar to the above, but with integrated graphics. After KM133, DDR is supported. The KM133 uses an IGP consisting of the S3 Savage4 3D core and Savage 2000 2D functionality. KM266's ProSavage8 IGP is similar but has an additional 3D pipeline. The KM400 chipset and its "A" variant use the VIA UniChrome IGP. KM400A supports FSB 400 unlike the KT400A
Later revisions of the KT333 (sometimes called KT333CF) are rebadged KT400 chips with AGP 8x disabled. On motherboards with this chipset AGP 2x cards which require 3.3V are not supported.
KT133E (= VT8363E + VT82C686B) appears on Gigabyte 7IXEH ^[21] but is not listed on the VIA site. Based on the specifications of that motherboard, KT133E appears to be equivalent to (or a cost-reduced rehash of) KT133, supporting 133 MHz for memory but only 100 MHz for the CPU.
Some revisions of KT333 support 166 MHz FSB.

Being a reduced version of PM880, PM800 is not as closely related to PT800 as P4M890 to PT890. Because of its high cost, It is soon obsoleted in favor of P4M800 and then P4M800 Pro, both of which have a lower rated V-Link and feature no special memory technology such as FastStream64 or StepUp that is common in the other listed 8xx chipsets.
VIA PT890, P4M890, PT900, P4M900 – VIA's PCIe-only chipsets. The P4M chipsets have onboard graphics VIA UniChrome Pro.

VIA K8M890, K8T890, K8T900 – VIA's PCIe-only chipsets.
The K8M800 chipsets has the onboard graphics VIA UniChrome Pro; the K8M890 has the Chrome9.
The Athlon 64 chipsets do not have memory controllers, because memory controller is integrated into the CPU. Supported memory types depend on the CPU and socket used.

The SATALite interface allows for two additional SATA devices (4 total) with use of a PHY chip which occupies the secondary PATA channel. It is required for RAID 0+1 on VT8237R Plus.
The VT8237 and VT8237R do not support SATA speed autonegotiation and will not work with SATA-II or III drives unless the drive has a compatibility mode jumper set. ^[69] The VT8237R Plus supports SATA II drives but only at the 150 MB/S speed.
The SATA-II feature of VT8237S is limited to 300 MB/S Data Transfer Rate bearing no NCQ functionality.
Motherboards frequently had VIA companion chips for added functionality such as better audio (8 channel), more/faster USB (i.e. USB 2.0 for VT8233), or Gigabit Ethernet.
The software modem is supported through a MC'97 or HD Audio codec chip and requires external components to implement the electrical connection to the telephone line. This circuitry may be included on the motherboard directly or added through a communications riser slot.
The chipset Ethernet MAC requires an additional PHY chip. Some vendors opted to add a MAC and PHY from a different manufacturer instead of using the chipset's built in capability.

Hardware bugs

The KT133 chipset corrupted disk subsystems; specifically, the 686B Southbridge had issues with Creative's SBLive! sound cards. A BIOS update was released by VIA to fix this issue; however, it is not known if all motherboards with 686Bs had their BIOSes updated.^[70]^[71]^[72]^[73] The KT266 contains a hardware bug which can cause system instability when using the AGP slot at the 4× speed.
