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 (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.

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, V-Link works at 533 MB/s and there is official support for 333 MHz FSB.
