drkohler said: Too many mistakes in your answer, so again I reapeat: The HD7770 GPU is a 125mm^2 die. The HD7950M GPU you apparently want to see is a 350mm^2 die. Your chip is almost three times larger (translation: three times more expensive) than mine. You lose instantly and permanently. The 384bit bus width of your chip kills the idea instantly, too. Even 256bit is at the edge of possibility, your PCB just gets too expensive (7770 is 128bit). The idea that any OEM buys a huge, expensive chip (7950) that is then downclocked/castrated (7950M) to perform roughly the same as a small chip is ridiculous. Not going to happen. Again I repeat: every mm^2 counts, every additional PCB layer (for wider busses) counts. The 7770 chip is the cheapest GPU that is good enough for 1080p/60Hz. The AMD FX8... series of processors is ideally suited for XBoxNext due to its design pecularities - I must remember everyone that XBoxNext has to perform two entirely separate things in parallel: run games and run Kinect2. What GPU MS will use is anyone's guess at this point (unless you have the latest dev kit). They have all the money to go 78xx if they want to. At this point we have rumoured to (performance estimate in %): WiiU: triple-core PPC and dedicated (heavily modified) 4850 type GPU (100%, about 130% PS3/360) PS4: A10 APU (70-90%) PS4: A10 (for physics, move etc) with dedicated GPU in the 7770 range (150-170%) XBoxNext: FX8xxx with dedicated GPU in the 7770 range (170-220%) Yes, I know nobody will like my estimates. You's rather read that PS4/NextBox will be 6 times more powerful than WiiU. Not going to happen. Ever. |
I just disagree in one part... the Wii U GPU seems more like a RV740 downclocked... HD 4770 with low clock.
And PS4 needs another GPU or these rumores are all fake.
