It was most convenient for Nintendo to keep it PPC750 based though, that meant that to run Wii games they just had to use one of the three cores, downclock it to Wii speed, and use only 256kb of its L2 cache.

I do agree that it is an underestimated part though, and that with its GPGPU the console was clearly designed for share the load of traditionally CPU-assigned tasks.

From what I understand  Powerpc 476fp could have been used. At the end of the day it is a custom power based chip so maybe a little of this and a little of that could have been used. Also, in development of the Wii U they pondered a 1+1 but, chose not to. So I think the CPU they decided on was strong enough with out the need for that when used properly.

If it's strong enough to run games like Bayonetta 2, X, and Pikmin 3, then it's strong enough for me.


Wii's CPU was strong enough on it's own, and, even though the Wii U CPU isn't just three Broadway processors overclocked like some people here think, even if it was, it would be easily better than the 360's CPU. The 729MHz Broadway core was almost as fast as one core at 3.2GHz in Xenon, since it used a much shorter pipeline and was and out-of-order design, compared to PS3/360 processors that used a in-order design and long pipeline(much like Atom and ARM11 processors). Wii U's CPU certainly isn't a problem, it is surely stronger than Xenon, developers complaining about low performance on it clearly were using code optimized for high clock/low IPC cores of the PS3/360, which obviously won't work well on a low-clocked/high IPC design.
