Espresso (processor)
Espresso is the codename of the 32-bit central processing unit (CPU) used in Nintendo's Wii U video game console. It was designed by IBM, and was produced using a 45 nm silicon-on-insulator process. The Espresso chip resides together with a GPU from AMD on an MCM manufactured by Renesas. It was revealed at E3 2011 in June 2011 and released in November 2012.
