Chapter 6 Integrated Graphics Subsystem

6.2FUNCTIONAL DESCRIPTION

The NVidia NForce 220 chipset includes a graphics processing unit (GPU) integrated into the integrated graphics processor (IGP) component (Figure 6-1). The graphics controller can directly drive an external, analog multi-scan monitor at resolutions up to and including 1920 x 1440 pixels. The GPU includes a memory management feature that allocates portions of system memory for use as the frame buffer and for storing textures and 3D effects.

These systems may be upgraded by installing a separate AGP graphics card in the AGP slot, which disables the onboard IGC.
