[QUOTE="04dcarraher"] Even if they could fit a 7950 type gpu into the PS4 it still wouldn't do 4K resolution games without sacrificing alot .04dcarraher
Rendering current games at 4K resolution, it would need two 7950s @1Ghz or one 7950 @ 2Ghz (for VRAM, it might need XDR2 or yet another GDDR5 revision). My fastest overclock for my 7950 is clocked at 1.2Ghz with 1.2V (sounds like a jet turbine at this level, temps at ~90C).
4096 x 3072 = 12,582,912 pixels.
5760 x 1080 = 6,220,800 pixels.

For PS4 with direct replacement parts from PS3
PS3's CELL = replaced by AMD Liverpool APU with AMD Radeon HD 7850 IGP i.e. AMD GCN acts like SPEs, X86s acts like PPE and ARMs acts like SPE DRM processor.
PS3's RSX = replaced by AMD 7950 GPU.
You don't have the initial blu-ray R&D cost.
The key technology would be 20nm process technology.

MS's Xbox 720 (Yukon) looks like using AMD Liverpool type APU(application) with AMD Jaguar APU (system).
Bill of materials wise, Xbox 360 is cheaper than PS3.

Gaming PCs not restricted by console budgets e.g. 20 nm TSMC fab'ed flagship GPUs e.g. Radeon HD 9970/10970 or Geforce GTX 880/980.
Wont happen in a console1st generation PS3 CELL's die size is 235 mm^2.
1st generation PS3 RSX's die size is 240 mm^2.
AMD Trinity's die size is 246 mm^2 (32 nm process tech). Half of it allocated towards quad CPU Piledriver cores i.e. about 123 mm^2.
With 20nm process tech and the above PS3 die size budget, it can support quad core Piledriver, one Radeon HD 7870 GPU and one 7950 GPU..
