Nintendo Wii U (Project Café) and T2/Linux

The Nintendo Wii U is the successor of the Nintendo Wii, and uses a custom multi-chip module (MCM) developed by AMD, IBM and Renesas in co-operation with Nintendo. The MCM combines an "Espresso" central processing unit (CPU) and a "Latte" graphics chip (GPU), as well as a SEEPROM memory chip.

• PowerPC 750-based, tri-core CPU w/ 3 MB of shared L2 cache and clocked at ~1.24 GHz
• Latte "GX2" GPGPU, designed by AMD, based the Radeon R600/R700 architecture, at ~550 MHz
• 32 MB of eDRAM cache memory, can also act as L3 cache for the CPU
• 2 GB of DDR3 system memory
• 8 GB (Basic) or 32 GB (Deluxe / Premium) internal eMMC flash memory

Additional expansion options include:

• SD memory card slot
• 2 USB 2.0 ports
• 802.11b/gn Wi-Fi
• Bluetooth 4.0

Notes

Due to cache coherency issues currently only one CPU core can be used in Linux and the AMD GPU is not yet utilized.
