GPU aka GPGPU
r700 based at 40nm
We have performance per watt figures for a r700 base gpu at 40nm.
4770 at 40nm is 12 glfops per watt is 137 mm˛ die with 826m
edram takes up at least 37 mm˛ and the wiiu gpu is 156 mm˛.
That leaves at most 100-110 mm˛ for the gpu. Since you have other thing on the die also.
So now we have the power number, gpu on 40nm process and still a r700 based. Man I called all of this....
If you used the whole 33 watts for just gpu you are looking at 396 gflops which is impossible.
More likely using 20-25w at most for gpu, so you have a range of 240 - 300 glfops. Xbox 360 and ps3 are 240-250 gflops.
