ZoyosJD stop making things up.
PS4 specs and architecture has already been confirmed. Yes it's true that the CPU is basically 2 APU CPUs together but it's paired with 1 GPU alone. Just because it will have 2 APU CPU working as 1 doesn't mean that both will have its own GPU.
The PS4 will have a 3rd chip (and even a 4th one if I remember correctly to decode video without the help of the GPU) based on Arm to run the OS so the APU (which is 2 quad-cores paired with a GPU in the same die) will be only turned on for games. This is a really smart design when you think about it, because the OS, movies and all PSN features will play on their own dedicated low power chip which mean less heat and incredible power saving when not playing games. On top of it the APU will be 100% dedicated to games so developers will be able to squeeze every bit of performance out of it without having to worry about cross-game chat, in-game video chat, in-game menu, etc.
And there's more, because the CPU and GPU are on the die I would even expect the console itself to be smaller than the current PS3 super slim. And not to mention that because they are on the same die the communication between them will be faster than having to connect to a northbridge, and all that is paired with unified high-speed memory. Which mean that GPGPU computation will be more efficient than the Wii U's or any other device including the PC. The PS4 architecture is so amazing it doesn't has bottlenecks like the PS3 had with the GPU and memory where the Cell was super powerful but could never be used to its fullest potential. Everything on the PS4 is completely balanced to not waste anything. Well.... The bottleneck will be the blu-ray's drive speed and the hardware itself due to its immense amount of memory if developers don't find uses to it. lol
[but 1 thing is for sure, PS4 will be worth every penny and I think this is why MS has been so reluctant to show the next-Xbox. I bet they are making lots of last minute adjustments to the hardware right now by copying what they have seen of the PS4's HW architecture] Full specs of the APU CPU here:
eight Jaguar cores at 1.6 Ghz, arranged as two clusters
Each cluster contains 4 cores and a shared 2MB L2 cache
256-bit SIMD operations, 128-bit SIMD ALU
SSE up to SSE4, as well as Advanced Vector Extensions (AVX)
One hardware thread per core
Decodes, executes and retires at up to two instructions/cycle
Out of order execution
Per-core dedicated L1-I and L1-D cache (32Kb each)
Two pipes per core yield 12,8 GFlops performance
102.4 GFlops for system
(Cell = 230.4 GFlops)
