IBM is still being quite secretive about the multi-core CPU it is providing for Nintendo's Wii U, but details are slowly leaking about what it has under the hood. The "Watson" chip is said to be a custom Radeon GPU, and while it's not exactly cutting edge it is capable of surpassing the output of the Xbox 360 and PS3. The chip is similar to the R770 found in AMD's last-gen cards like the 4890, but he custom core also supports Direct X 10.1, whereas the Xbox 360 can only run Direct X 9. It also supports an Eyefinity-like multi-display tech for up to four SD video stream, something Nintendo was being wishy washy about at e3. So it is a powerful system, but not cutting edge. These are not final specs however, and are subject to change before launch next year.
