I'd just sign with PowerVR (with ARM CPU) to be honest. There was a rumor about a year ago that Nintendo from acccepting hardware pitches from PowerVR/Imagination in addition to AMD.
Very, very hard to beat 800 GFLOPS at only 6 watts or so. That's insane. Put some high speed eDRAM in a custom design on that sucker and you have a pretty nice chip for Nintendo and one that scan scale up and down to portable and home version as needed.
It's also apparently very cheap, PowerVR operates in huge volume because they supply Apple for the iPhone/iPad, likely they can give Nintendo a price even AMD can't beat.

Very, very hard to exist 800 GFLOPS at only 6 watts or so, you do mean. I hope you are aware 99% of the time portable SoCs ran at half speed or lower of their theoretical capacity. Iris Pro 6200 is more likely to ran at actual 800 GFLOPS and probably consumes the beefier part of the 65-95W TDP of the newest Intel 14nm chips, for instance. Unless PowerVR is running "fake"-FLOPS like TeraScale or the older PowerPCs, meaning lots of raw number-crunching, but not even as remotely efficient as chips from different architectures with similar FLOPS count.
For mobile designs, strangely the 28nm Snapdragons are still at or very near the crown on terms of efficiency, so maybe Nintendo could base something off that, if they forego AMD, which I don't think it's going to happen, even with the news increasingly pointing to a more mobile, Android-like design.
