Compute shader support
GX2 is a 3D graphics API for the Nintendo Wii U system (also known as Cafe). The API is designed to be as efficient as GX(1) from the Nintendo GameCube and Wii systems. Current features are modeled after OpenGL and the AMD r7xx series of graphics processors. Wii U’s graphics processor is referred to as GPU7.
Sound and Audio
Dedicated 120MHz audio DSP.
Support for 6 channel discrete uncompressed audio (via HDMI).
2 channel audio for the Cafe DRC controller.
Monaural audio for the Cafe Remote controller.
Networking
802.11 b/g/n Wifi.
Peripherals
2 x USB 2.0 host controllers x 2 ports each.
SDCard Slot.
Built-in Storage
512MB SLC NAND for System.
8GB MLC NAND for Applications.
Host PC Bridge
Dedicated Cafe-to-host PC bridge hardware.
Allows File System emulation by host PC.
Provides interface for debugger and logging to host PC.
该网站表示根据任天堂给开发商的工具包具体研究得出上述具体规格，另根据发热量大小及可能采纳的制程，推测WIIU的GPU将采用基于AMD Radeon E6760 特别定制的显卡，联系早前任天堂官方承诺WIIU在下一代主机性能之争的差距不会像本世代明显，WII U的GPU性能有可能如原作者描述的那样，直接比肩下代PLAYSTATION或XBOX。
