All 3 wii , PS3 and X360 use power PC to start with.
The 128bit x128register design of the ALTIVEC SIMD units on the X360 Xenon CPU and the Cell's SPU's also have 128bit x128register are a common feature which is not seen before on previous power chips design sharing it's quite obvious. What you would expect since they both came from IBM, i was impressed with both chips but the Cell more so since it is so extreme no more of the older slow parts of the Power Archecture it's SPU's are pure SIMD with multi core, crunching and logic.
Aside for that turns out the CPU & GPU is not what next-gen is about - most users could not care less. Nintendo turn out the be ones with the only next gen console by putting their research into something even more important the "total user experience".
At the end of the day if your new super computer is not user friendly and fun it will end up in the bargain bin ! - Microsoft and Sony have been tasting defeat in the face of the Wii. Even the bargain bin X360 arcade has done nothing to slow the Wii's market domination.
