Configurations
The VIA Apollo Pro consists of two devices. For high performance,
power-conscious desktop and mobile designs, the VT82C691 combines with
the new VT82C596, a BGA-packaged southbridge with a full set of mobile
power management features. For cost-effective, high performance desktop
designs the VT82C691 can also be configured with the VT82C586B south
bridge.
Backward Compatible
Backward compatible, the VIA Apollo Pro offers PC users a clear upgrade
path to emerging 100MHz processors and DRAMs, but with the option to mix
and match 100MHz clocked SDRAMs with 66MHz SDRAMs.
3D Game Power
Apollo Pro continues VIA's leading role in the development of
AGP-enabled core logic chipsets. VIA's close development efforts with
the full range of leading AGP graphics vendors ensure that the Apollo
Pro delivers leading-edge 2X AGP graphics capabilities for the full
range of graphics intensive games and programs.
