CPU: IBM Custom PowerPC 3.5 GHz + 4 internal Power PC G5 cores running at 2.5 GHz each. Each core will have 128 KB or 256 Kb L1 cache. The whole CPU will share 512 KB - 1 MB of L2 cache. As you can see they are deciding wether to go up one notch. But never the less, its a very powerful CPU with 4 custom G5 cores.
There will also be two hardware threads per core, 8 hardware threads total.
12 billion dot product operations per second
Theoritical of 10 GHz total + 3 GHz CPU speed
Xbox 360 CPU:
Three symmetrical cores running at 3.2 GHz each = theoritical of 9.6 GHz + 3.2 GHz CPU speed
Two hardware threads per core; six hardware threads total
VMX-128 vector unit per core; three total
128 VMX-128 registers per hardware thread
1 MB L2 cace
Revolution GPU
ATI Custom based RN520 core. the "N" stands for nintendo, and is because the ArtX team is with them, thats why its an "N". There will be 2 GPU cores (just like the nVidia SLI motherboard with two Graphics Chips), this will use ATI's alternative, and will be the first in any console.
Both GPU's will have 256 MB's of GDDR4 memory, with an addional 16 MB of eDRAM total. eDRAM is an onboard flash memory, just like the 3 MB on
the gamecubes flipper.
The cores will run at 600 MHz each, (rumours are that its possible 500 MHz each), but i doubt that.
24-to-48 way parallel floating-point dynamically scheduled shader pipelines for each core with unified shader architecture.
Polygon Performance: 500 million triangles per second theoritical, average ingame would be around <100 Million/sec
Shader Performance: 48 billion shader operations per second
Revolution memory
512 MB of 700 MHz Updated 1T-SRAM (its a totally redone design of something new, remember the nitrous i talked about)
Also, as I said I’m going to add more info, the Revolution will support a PPU chip (Physical Processing Chip). This chip is very new to computer architecture, and it will mainly help in the physics area. There will be 32 MB’s of its own RAM, which will link to the CPU and GPU. To compare to the usage of physics used in current games, Half Life 2 only used 5 MB’s, Rebel strike used around 1.3 MB’s, and RE4 used 3 MB’s, but this is off main memory, which made performance issues.
There will also be a separate sound card that will support only DD 5.1 – DTS 7.1, rumours has it will have 16 MB’s, like the Cube DSP.
competitive with 360 and PS3.
