We've talked about AMD powering the PlayStation 4's GPU, but what of it's CPU? The PlayStation 3 had Sony running parade's around the world (ok, well, not really) about it's revolutionary Cell processor, but after the PS3's release, developers said it was harder to code for.
Now that Sony would be at least piecing the puzzle together that will eventually be the PlayStation 4, rumor has it that the Cell processor, which was once the be-all-and-end-all of chips from Sony (and others) will not be making the cut, according to unnamed sources of Kotaku.
Considering AMD will most likely be building the GPU for the PlayStation 4, one would think they've either use a combination CPU/GPU chip, or would at least slap a 6- or 8-core CPU on the new PlayStation 4. I think that would work well, as cross-platform development would be insanely easy compared to today. If the three main consoles all use AMD-based GPUs (which it seems to be the case), then we should expect much better PC ports of the games, in theory.
