List of VIA chipsets
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 and VIA themselves. 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.Socket 5 and Socket 7

- 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.
Socket 8, Slot 1 and Socket 370
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 - graphics core from S3, derived from S3 Savage series under the brand name UniChrome.- Asus advertised some boards as Apollo Pro 133Z. 133Z appears to be a late revision of or step up from 133A, but it is not listed on the VIA site.
Slot A and Socket A
- KT266 contains a hardware bug which causes system instability when using the AGP slot at the specified max capacity of 4×.
- 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 are rebadged KT400 chips with AGP 8x disabled. On motherboards with this chipset AGP 2x cards which require 3.3V are not supported, V-Link works at 533 MB/s and there is official support for 333 MHz FSB.
- KT133E is a cut-down/cost-reduced version of the KT133A without official support for 133 MHz FSB. It was develeoped to replace the original KT133 when it went out of production.
Socket 423, 478 and LGA 775
- 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.
Socket 754, 939, 940, AM2
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 K8M890 was also used on boards with Socket 754, like the ASUS K8V-VM Ultra

- The VT82C686A/B and VT8231 support hardware Sound Blaster Pro compatible sampled sound, and FM synthesis emulation through use of a TSR.
- The SATALite interface allows for two additional SATA devices 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. 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, more/faster USB, 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 could be included on the motherboard directly but was typically added through a communications riser slot.
- The chipset integrated 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.
