Wii U, was finally unveiled to the world today at E3 2011, and we got a glimpse of its graphical prowess at the company's keynote. Details were scarce about the IBM silicon Nintendo's new HD powerhouse was packing, but we did some digging to get a little more info. IBM tells us that within the Wii U there's a 45nm custom chip with "a lot" of embedded DRAM (shown above). It's a silicon on insulator design and packs the same processor technology found in Watson, the supercomputer that bested a couple of meatbags on Jeopardy awhile back. Unfortunately, IBM wouldn't give us the chip's clock speeds, but if it's good enough to smoke Ken Jennings on national TV, we imagine it'll do alright against its competition from Sony and Microsoft.
