The figure illustrates a block diagram of a “graphics processing system” that supports oversampling anti-aliasing. The system includes a graphics processor (GPU), a sample memory (the standard memory on today's video cards) and a custom memory module (the embedded RAM).
This custom memory has been created mostly to perform anti-aliasing operations and help overcome today's biggest problem in graphics: memory bandwidth. By using this embedded RAM, which is similar to a processor's cache memory, the Xbox 360 will be able to run games at 720p HDTV resolution, that is 1280x720, with full screen anti-aliasing and almost no impact on framerate.
