Well I thought it was a Radeon HD 6400. I'm still fairly sure its a mobility radeon design. The HD 6400 only has 4 rops though. The thing is you wouldn't normally have 8 texture units and 8 rops so I still think they have this wrong and it is a HD 6400.
I really think Nintendo would have used a mobility radeon. It makes complete sense with the size of the wii u and the Radeon HD 6400 is a perfect fit.
