I have argued many times that it is more likely that Nintendo and/or Microsoft would have GPUs with similar performance to a laptop GPU than something from the desktop side of things; and it is likely that Nintendo has a GPU between 500 GFLOPs and 750 GFLOPs of processing power, while it is likely Microsoft will have a GPU with between 1TFLOP and 2TFLOPs of processing power.
The actual chip Microsoft chooses will largely depend on what price range they want to target at release and whether they want to bundle Kinect (or something) with the system. If they're targeting $300 unbundled I could see a 1TFLOP GPU, and if they're targeting $500 bundled I cold see a 2TFLOP GPU. |
It seems that WiiU, when fab and die size is taken into account, has between 352 and 528 GFLOPS (320 to 480 shaders@550MHz). Initial NextBox rumours were some 6x as 360, later rumours are 8x 360, which would be 1440 and 1920 GFLOPS respectively, if they took GFLOPS as comparison (that would be 7770 GHz Edition and 7870/7970m@750).

Power constraints would mean that a 7950/7970 derevative would be unlikely. But then the Xbox 360 was based on the following generation's GPU from ATI which hadn't been released at the time.
So, power requirements Vs performance will be lowered as per standard for all GPUs over generations.
My bet's on a cut down 8xxxx desktop design.
Mobile chips are aimed at the seriously power starved laptop platform, the next Xbox 360 and PS will easily be able to handle a TDP of 125W for the graphics card. Going for a mobile derevative simply isn't needed.
