first of all about the gamepad when mirrored come for free, meaning does not tax the hardware, second of the memory bandwidth is confirmed 100%, and about the 30% of the board unknown, is probably because we never had a console with a tablet and BC, those are probably functions for them to work properly on the gpu, because like i said before there is no technoloy to make a gpu even 25% more powerful based of the logic, which doesn't even have enough sram for it.

Gamepad in Sonic Racing isn't just a mirror of the main screen. And in multiplayer, it supports an extra player on the gamepad, while holding the same FPS as the PS3. Given that the computational power for higher resolution is smaller than the computational power for an extra 'camera' (in-engine camera, that is), it makes a difference.

Regarding memory bandwidth... no, it's not confirmed 100%, any more than the number of SPs is confirmed 100%. It's believed to be a certain number. And just because you speculate that the unknown 30% is for tablet and BC, doesn't make it true or a good reason to assume anything.

And there is no technology in any current GPU that would have a significant impact. That doesn't mean that such a technology doesn't exist.

But then, I'm curious as to your explanation for how the Wii U is able to draw so little power. Even at the 40/45nm scales, the PS3 and 360 both draw 60+ watts of power. The Wii U, which we can be confident is at least as powerful as those two systems, is doing so at about 32 watts peak power draw. More typical numbers for active use put the Wii U at 32 watts when both other systems are over 70 watts. What is your explanation for this particular observation?

here is a confirmation of the memory bandwidth, it's not speculation at all http://www.anandtech.com/show/6465/nintendo-wii-u-teardown my explanation is simple, wii u is based of newer, more efficante technoloy in watt usage.

 


Power usage this is what we got?

33 watts max from wall @ 90% psu ~30 watts

Disk drive ~4 Watts Cpu ~8 watts

Whats left ~18

My guesses,anyone have hard numbers?
2GB DDR3 Ram ~2 Watts 
wifi ~.5 Watts 
Flash Storage/misc .5 Watts

Leaves about 15 watts for the whole gpu chip

Its very impressive that this little bit of power can keep up with the ps360
