VIA chipsets

VIA MVP3 - Popular Super Socket 7 chipset, with AGP interface 1.0, up to 512MB of PC-100 SDRAM, and up to 2MB L2 cache. Updated to MVP4 with integrated Trident graphics and improved ATA-66 disk interface.
Apollo Pro133 - The first VIA Intel chipset to support a 133 MHz FSB (Slot 1/Socket 370), and perhaps most importantly, supported 133 MHz SDRAM memory. The Apollo Pro133A featured AGP 4X support.
Apollo Pro133A, Apollo KX133/KT133/KT133A - The Apollo KX133 was a derivative chipset for the AMD Athlon, Slot A. Following that came the Apollo KT133 for AMD Athlon/Duron, Socket A. The chipset was revised to the KT133A spec, featuring memory controller tweaks, and improved features. The KT133A proved a popular chipset with stability and performance.
ProSavage PM133/KM133 - Based upon a graphics core from S3, derived from a combination of the 3D-component of Savage4 and 2D from Savage2000. They were VIA’s first in house integrated chipsets.
VIA KT266, VIA KT266A, VIA KT333, VIA KT400, VIA KT400A, VIA KT600 - A DDR memory refresh for the Athlon processor. The A spec part was notable for delivering an unexpected speed improvement. Subsequent versions updated to more recent memory speed grades, reflected in the chipset titles. Finally, KT880 matched the dual channel memory of the nForce2 chipset.

VIA K8T800, VIA K8T800 PRO - Athlon 64 chipsets. Established an early market lead, with richer features, and a full speed HyperTransport implementation
VIA PT880, K8T890 - Via's first PCIe chipsets (Pentium 4, Athlon 64)
