Ah, the Megahertz Myth. I remember this old fallacy from back in the 90s, and I can't believe people STILL think clock speed = power.

Each Wii U core takes up no more than 1/3 of the area of a 360 core. It is therefore not faster per-clock, unless a miracle happened at IBM. Performance = clock speed * performance per clock (approximately, yes it's a tautology).

To use an example from the 90s, would you rather have a 600MHz Pentium III or a 1.6GHz Pentium 4? The Pentium III was faster per-clock, but the difference is so big that you'd obviously get the P4.

Size is also not necessarily a cast-iron indicator of power; there's other factors. (Latency, GPGPU) This hacker fellow already said that comparing it to the 360 CPU and surmising it's much weaker is a mistake. 

OK.

I'm only gonna say this once.

Fuck GPGPU.

Pretend it does not exist. There are a large number of reasons for this.

Apart from that, YES, the CPU is not the only factor in the system. But all the info we have (die size, clock speed, approximate architecture, resulting games) indicates that it is the major bottleneck to performance. That is the only point I am making here.

He said that assuming it's much weaker (as in, lol 1/3 of the clock 1/3 of the performance) is a mistake. He hasn't said whether it's stronger or weaker. I think the evidence still means it's weaker and that is a problem.
