Curious about what silicon is powering Nintendo's Wii U? So was Anand Lal Shimpi, who tore his brand new console to pieces in the name of science. At its heart is a multi-chip module with a PowerPC-based CPU, built on IBM's 45-nanometer process, paired with a GPU similar to AMD's RV7xx design. These two components share 2GB of DDR3 RAM (plus an unspecified amount of eDRAM), while Anand calculates memory bandwidth to be 12.8GB/s. That's around the same as as the
