The Wii U is 64 bit Power 7 fundamentally.
It can also handle 32 bit operations like any Power 7.
And no, the Wii U isn't 4 over-clocked Wii CPU's on one die... Power 7 hasn't been around for 10 years but only existing as a single core...
Some of the logic used to deduce info is startling.
Also 1 of ur links says that ps3 is 8 cores.. thats wrong.. It is 1 core and 8 threads.. lol and hard to program. http://wiiuconcepts....pu-exposed.html
Actually, that is wrong too.
The "SPEs" as Sony likes to call them are actually only 7 active vector processors. There are 8 physical, but sony had to disable one due to yield issues which seemed to turn up a dead SPE more often than not during Cell manufacturing when it came time to lock in the PS3 spec. so the Ps3 has one "Core" PPE and 7 effective vector units.
