About this component
Latte is the large die on the Wii U's MCM. Besides the Radeon-derived GPU it carries 32 MB of eDRAM used as fast MEM1 (and usable by the CPU), extra 1 MB and 2 MB SRAM blocks for Wii compatibility, and the Starbuck security processor, a successor to the Wii's Starlet. A dead Latte means replacing the whole MCM or board, as the dies cannot be replaced separately.
What it does on this board
550MHz Radeon-based GPU with 32MB eDRAM, on the same MCM as the CPU.
