VIA KT133 - The Market Leader for Mainstream Socket A Platforms

The VIA Apollo KT133 was the first chipset available supporting Athlon™ and AMD Duron™ Socket A processors. In terms of price - performance and scalabiltiy it is widely recognized as the leading chipset of its type, and has ensured that VIA - AMD based platforms, with their superior value and compelling feature sets, blaze a trail for others to follow.

The VIA Apollo KT133 chipset unleashes the full performance potential of AMD's Athlon™ and Duron™ Socket A processors by providing an extensive high-end feature-set that includes 200MHz FSB, AGP4X, PC133 memory and ATA-66. The AGP4X interface enables the graphics controller to access the main memory at double the speed of previous platforms, ensuring rich 3D graphics and video performance on your AMD processor-based PC system. The ATA 66 interface on the VIA Apollo KT133 chipset helps boost system performance by providing a high-speed connection to powerful ATA 66 Hard Disk Drives, delivering maximum sustained data transfer rates of 66MB/sec.
