Also, neither Sony nor MS would ever use a desktop-based GPU in a console. It will be a mobile version. For example, HD7850M uses about 32W of power, while HD7950M uses about 50W (that's basically a slightly downclocked HD7870). 

The only thing stopping MS or Sony from dropping ~ HD7870 (HD7950M) part into their next console is cost, not power consumption. A10-5700 + HD7950M would be a much fit for a next generation console for well-rounded graphics than FX8xxx + HD7770, but it sounds like Sony is now run by accountants not gamers. I at least hope they do include some kind of a dedicated GPU or the console is in trouble if the A10 APU is all that it has.

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.

Even ethomaz's correction of the Radeon HD 4770 produces 960 GFLOPS, which is exactly 4 times the performance of the XBox 360 GPU.

I just disagree in one part... the Wii U GPU seems more like a RV740 downclocked... HD 4770 with low clock.

Based on what? You've been saying this for a while now and your only reasoning seems to be launch games.

The HD 4770 runs at 750Mhz... I said a RV740 downclocked to 500Mhz... at max 600GFLOPs... in line with the rumors.

Wii U board and it's components size plus all the info release for now... I already explaned that two or three time in this topic.

While there are multiple options in the Radeon 6xxxM and 7xxxM lines that are based on the Turks core, are manufactured using a 40nm process, have 480 stream processors, and run between 25 and 40 Watts (all things that match most of the rumours) the fact that they all have between (roughly) 600GFLOPS and 700GFLOPS of processing power gives us a pretty good idea of what Nintendo could do by picking one of these GPUs as their base. Even the desktop GPUs that match this profile (Radeon 6570, 6670, 7570 and 7670) all still run in the 600 GFLOPS to 800 GFLOPS range, although their wattage is higher (in the 60 Watt range).

Ultimately, we can argue endlessly about what the Wii U GPU might be based on, but I think it is fairly clear that it is probably (about) 3 times the performance of the XBox 360 GPU; and there is probably some increased efficiency and better features that come from being a more modern GPU.
