Good post.

Every time this topic comes around, there's always some moron who spouts a bunch of nonsense and puts out the myth that the WiiU's internals are exactly the same as the GameCube's.

The way I've always heard it described is:

Wii processor is an overclocked GameCube processor, Wii U processor is a reconfigured Wii processor, therefore the Wii U processor is an overclocked, reconfigured GameCube.

But the same is true for every x86 processor, they are in a way all overclocked and reconfigured 8086.

No, not really. Modern x86 is compatible but works completely different (µ-ops, different pipelines, branch-prediction, totally different instructions,...).

Yes, that is true. But you can say similar for Nintendos CPU. We know it is no vanilla PowerPC, at least in Gamecube and then again in Wii they added additional instructions. Probably the same is true for WiiUs CPU. We don't know much besides that, but it is more than possible that they overworked pipelines and branch-prediction too.
