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 then listed in a table at the end of this page.
Background and History.
Currently (~2020), most VIA chipsets are consider legacy/mature or obsolete. VIA chipsets were alternatives to Intel's own chipsets; or supported AMD cpus (e.g., Athlon-K8) and even VIA's own processors (e.g., C3 / C7). They supported CPUs as early as the i386 in the early-1990s. In the early-2000s, the chipsets offered on-chip graphics support from VIA's joint venture with S3 Graphics beginning in 2001 and continued to be active into the early 2010s, with release of the VX11H in Aug-2012. Use of VIA chipsets diminished beginning the mid-2010s as alternatives offered better performance, VIA entered other markets and Intel began offering better performing integrated-graphics in their own chipsets and cpu-dies. (See Intel GMA and Intel Graphics Technology.)
VIA Chipsets by CPU Socket / CPU Family.
Note: where the term "V-Link" is used in the tables below, it indicates VIA's northbridge / southbridge interconnect bus.
Socket 3.
Some Socket 3 chipsets (north and south bridges) were:
Socket 5 and Socket 7.
The following lists the VIA Chipsets supporting Socket 5 and Socket 7 cpus:
AMD licensed the VIA Apollo VP2/97 core logic architecture as its AMD 640 chipset.
Socket 8, Slot 1 and Socket 370.
The following lists VIA Chipsets supporting the Socket 8, Slot 1 and Socket 370 cpus:
Slot A and Socket A.
The following lists VIA Chipsets supporting AMD Slot A and Socket A cpus:
Socket 423, 478 and LGA 775.
The following lists VIA Chipsets supporting Socket-423, Socket-478 and LGA775 cpus. These are primarily chipsets supporting the Pentium-4 / Pentium-D family cpus, although a few early Intel Core architecture cpus are included:
Athlon 64.
The following lists VIA Chipsets support the AMD Athlon 64 cpus. The K8 series established an early market lead in support of the AMD Athlon CPUs, with rich features and full speed HyperTransport implementations:
Southbridge chips.
As a modular solution, the North and South Bridge of the VIA Apollo KT266A are completely pin compatible with current and future products, such as the VT8233C South Bridge with integrated 3Com Ethernet MAC.
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 cause system instability when using the AGP slot at the specified max capacity of 4×. [14]
