The Revolution will have little more horsepower than the original Xbox, IGN reports. They have spoken to a number of studios who wish to remain anonymous. Here´s the story:
IBM's "Broadway" CPU is clocked at 729MHz, according to updated Nintendo documentation. By comparison, GameCube's Gekko CPU ran at 485MHz. The original Xbox's CPU, admittedly a different architecture altogether, was clocked at 733MHz. Meanwhile, Xbox 360 runs three symmetrical cores at 3.2GHz. (...)
Revolution's ATI-provided "Hollywood" GPU clocks in at 243MHz. By comparison, GameCube's GPU ran at 162MHz, while the GPU on the original Xbox was clocked at 233MHz. Sources we spoke with suggest that it is unlikely the GPU will feature any added shaders, as has been speculated.
"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.
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.
It is not known if the 14MBs of extra D-RAM we reported on last December are in the current Revolution specifications.
"The external RAM can be accessed as quickly as the main RAM, which is a nice touch," a developer we spoke with alleged.
This news is hardly surprising - and shouldn´t make us expect any less graphics from the console when we will see games within the next few weeks (or quite possibly within days). After all, seeing how Nintendo managed to get Resident Evil 4 running on their current hardware, just think what wonders they could do with at least double that hardware power.
