The console features the IBM Broadway processor which is clocked at 729MHz and ATI's Hollywood GPU which is clocked at 243MHz.
"The 'Hollywood' is a large-scale integrated chip that includes the GPU, DSP, I/O bridge and 3MBs of texture memory," a studio source told us.More details over here.
The overall system memory numbers we reported last December have not greatly fluctuated, but new clarifications have surfaced. Revolution will operate using 24MBs of "main" 1T-SRAM. It will additionally boast 64MBs of "external" 1T-SRAM. That brings the total number of system RAM up to 88MBs, not including the 3MB texture buffer on the GPU. By comparison, GameCube featured 40MBs of RAM not counting the GPU's on-board 3MBs. The original Xbox included 64MBs total RAM. Xbox 360 and PlayStation 3 operate on 512MBs of RAM.
