Wii U hacked and CPU clock speed revealed, apparently.

[Soleron]

So much for "makes up with it with clock speed". Definitively slower in both clock speed and (if PPC750) instructions per clock compared to the 360.

It's now time to use the Wii U ports as a positive example: despite how slow the CPU is, they can make a game look about as good as the 360 because of the GPU. But it's also therefore time to stop saying that Wii U will eventually be far ahead of 360.
