Is it possible that we are looking at graphical power differences between all three consoles in the range of this (below) for next generation or will it be more broad? if wii u was using a 28nm gpu what would be the TDP for something along the lines of a 7750 equivalent in power designed for the console?
Radeon HD 7750 Wii U
Radeon HD 7770 XBOX
Radeon HD 7790 PS4
If we get a 7750 or 7770 in range of power for next gen I would be very happy for all three to be in that range and ecstatic if WiiU was even 7750 equivalent
I am not even sure if it is a given that the wii GPU will be over 1200GFLOPS in performance but if it is then would that be around 5 times more graphical processing than the GPU on the XBOX 360?
What would be the Max TDP the GPU would have to be to fit in the WiiU case? if it is under 66W for GPU then something like a 7750 in power would be out of the question. What if we looked at something in the mobility range and if tweaked it up to meet a power equivalent to about 5x the xbox 360.
5870M TDP 50W 40nm 1120GFLOPS
6950M TDP 50W 40nm 1113GFLOPS
What is the concensus on what TDP the WiiU is likely to consume? how much goes into the GPU-CPU-drive and other parts?
I'm expecting ~100w for the total console. One of the times we were looking at the POWER7, blu found documentation showing the cores at around ~23w (can't remember if that included to cache for the core). Knowing Nintendo I wouldn't be shocked to see theirs at ~10w/core, and the overall CPU being ~30-35w.
As for the GPU IMO the easiest way for Nintendo to reach 1.2TFLOPs would be a part that has 960 ALUs clocked at 625Mhz. And while I'm not saying it's impossible, there's been no indication that they were going in that specific route (e.g. over 800 ALUs), but just one mention that it was over a TFLOP. I've been expecting the GPU to be a part of an LSI like what Wii had and I can see that being ~60w since I believe it will be on something smaller than 40nm.
I don't know if it was posted before but spanish game sites and blogs are reporting that Mat Atkinson, former Director of Technology in Crytek is working in Nintendo as Consultant Software Engineer.
He worked in Lionhead and Ignition.

Apparently one of his achievements has been the adaptation of the CryEngine 3 to PS3 and Xbox 360.
Very nice find.
