VIA Apollo VP3 AGP Chipset - 66 MHz Front Side Bus

The Apollo VP3 is a high performance, cost effective, and energy efficient chip set for the implementation of AGP, PCI, and ISA in desktop and notebook personal computer systems based on 64 bit Socket-7 including; Intel Pentium and Pentium processor with MMXTM technology, AMD K5TM and K6TM, and Cyrix/IBM 6x86TM and 6x86MXTM super-scalar processors.

The Apollo VP3 chipset consists of the VT82C597 system controller (472 pin BGA) and the VT82C586B PCI to ISA bridge (208 pin PQFP). The VT82C597 system controller provides superior performance between the CPU, optional synchronous cache, DRAM, AGP bus, and the PCI bus with pipelined, burst, and concurrent operation. The VT82C597 complies with the Accelerated Graphics Port Specification 1.0 and features a 66 MHz master system bus.
