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 repeat:

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'd rather like to read that PS4/NextBox will be 6 times more powerful than WiiU. Not going to happen. Ever.


Just on your Wii U GPU ...

Were you aware that the GPU you selected for the Wii U is more than 4 times the processing power of the XBox 360's GPU?

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

 

Realistically, I think the Wii U's GPU is probably (something like) the Radeon 7690M XT which is (roughly) 3 times the performance of the XBox 360/PS3, is based on the Turks core, manufactured using the 40nm process, and runs at 25 Watts. Even the die size of the GPU at 118mm^2 falls roughly in line with what we would expect being that Nintendo added a bunch of eDRAM to the chip.
