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.

Socket 3

Socket 5 and Socket 7

All chipsets listed support a maximum cache memory size of 2 MB and are PCI 2.1 compliant

Socket 8, Slot 1 and Socket 370

Slot A and Socket A

Socket 423, 478 and LGA 775

Socket 754, 939, 940, AM2

Chipsets supporting both VIA and Intel processors

Chipsets supporting VIA processors

Southbridge chips

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. The KT266 contains a hardware bug which can cause system instability when using the AGP slot at the 4× speed.
