The retail GPUs AMD makes that are similar to this are the Radeon 7670M, Radeon HD 7690M, and Radeon HD 7690M XT which have performance of 575 to 700 GFLOPs |
If there is a 7670M GPU inside Wii U the raw power will not be 576 GFLOPS because the Wii U runs at 550Mhz and not 600Mhz... just that put the raw power near 528 GLOFS using this same GPU.
But there are other thing to look for...
The Wii U GPU have 156mm^2 with eDRAM... if you remove the eDRAM you have a dize size ~104mm^2... the 7670M "Thames" die size is 118mm^2. The best GPU that fits with the 104mm ^2 is the HD 5670 "Redwood" that have 400 shaders units... 400 SPs running at 55Mhz give us 440 GFLOPS raw power.
I don't know how many units have the Wii U GPU but you can't put more units using the same 40nm process... so the Wii U GPU will have between 400 and 500 GFLOPS... not more than that.
