A recent press release reveals that IBM will be manufacturing the new processor for Nintendo's Wii U console based on the computer company's Power Architecture technology. IBM also mentions that their embedded DRAM and Silicon insulator technologies will also feature in the 45nm processor's design.
IBM's Power Architecture family of technologies stretches back to the nineties and has been through many iterations. For example, the PowerPC architecture that eventually showed up in the processors for Nintendo's GameCube and Wii consoles was adapted from an earlier version of the technology. More recently, IBM's Watson supercomputer, designed to play and beat the world's greatest Jeopardy players, utilized 2880 multi-core processors based on the latest generation of IBM's Power Architecture processors.
Although the press release refers to the Wii U processor as multi-core, IBM did not reveal any details on the number of cores or processors that will be in the Wii U hardware, nor was there any mention of the processor's clock speed.
