Attendees at the In-Stat Fall Processor Forum here Tuesday got a preview of the of the custom-designed processor that will power Microsoft Corp.'s next-generation Xbox 360 game console.
The CPU comprises three 64-bit PowerPC cores, each running at 3.2GHz, "the highest core speed" ever achieved by this technology, according to Jeff Brown, IBM's chief engineer for the Microsoft CPU Project. Able to support two simultaneous threads, the processor was designed with the key goal of being able to support the high sustained bandwidth required by the game console. Brown said the processor should be able to hit a peak bandwidth of 21.6G bps.
