We have received info from an anonymous source. That comes from the Wii U devkit, so the specifications may change with the retail version (slightly). To sum up, you are not going to have a retail system more powerful than the devkit. Nintendo aren’t going to reveal that kind of information, but you can gain a valuable insight around Wii U specs.

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.
