Latte is the codename of the TeraScale-based graphics processing unit (GPU) and I/O chip used in Nintendo's Wii U video game console.[1] It was designed by Nintendo and AMD, and is currently being produced using a 45 nm CMOS process. The Latte chip resides together with a CPU from IBM on a MCM manufactured by Renesas. It was revealed at E3 2011 in June 2011 and released in November 2012.

Design

AMD and Nintendo have revealed that the Latte graphics chip is based on the "Radeon HD" series of GPUs, and is unofficially reported to be based on the R700 architecture. The chip also contains an audio DSP, eDRAM, DDR3 memory controller, I/O peripherals such as USB controllers, 32MB of eDRAM memory,[2] and components for Wii backward compatibility. Its GPU core is unofficially reported to be clocked at 550 MHz.[3][4][5]

Like the Hollywood, the Latte also contains an ARM926 core, which has been unofficially nicknamed the Starbuck.[5] As on the Wii, this microprocessor handles I/O functions and security.
