VIA Apollo MVP3 AGP Chipset 66/100 MHz Front Side Bus

The Apollo MVP3 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 from 66 MHz to 100 MHz based on 64 bit Socket-7 super-scalar processors.

The Apollo MVP3 chipset consists of the VT82C598AT system controller (476 pin BGA) and the VT82C586B PCI to ISA bridge (208 pin PQFP). The VT82C598AT 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 DRAM controller supports standard Fast page Mode (FPM), EDO, SDRAM, and DDR SDRAM. The VT82C598AT complies with the Accelerated Graphics Port Specification 1.0 and features support for 66/75/83/100 MHz CPU bus frequencies and the 66 MHz AGP bus frequency. Coupled with BDDR SDRAM II, the VT82C598AT allows implementation of the most flexible, reliable, and high-performance DRAM interface.
