An illustration of the Wii U MCM with heat spreader. The markings indicate that its designed by Nintendo, and its components are made by AMD, IBM and Renesas. It also says that it was assembled in Japan, the 26th week of 2012.
AMD and Nintendo have revealed that the Latte graphics chip is based on the "Radeon HD" series of GPUs. Although there have been several reports of the GPU being based on the R700 family of AMD GPUs according to older/early development kits from 2011, newer development kits in 2012 indicate it is/was based on Radeon HD 5000/6000 series since inclusion of Tessellation, Compute Shaders, Stream Out features and other features. Die shots reveal a completely customized design which resembles no older GPU. It is the largest die on the Wii U's MCM. The chip contains an audio DSP, eDRAM, and components for Wii backward compatibility.
