Looks legit, but time will tell:
Main Application Processor
Three cores (fully coherent).
3MB aggregate L2 Cache size.
core 0: 512 KB
core 1: 2048 KB
core 2: 512 KB
Write gatherer per core.
Locked (L1d) cache DMA per core.
Up to 3GB of main memory (CAT-DEVs only). Note: retail machine will have half devkit memory
Please note that the quantity of memory available from the Cafe SDK and Operating System may vary.

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 Uís 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.
802.11 b/g/n Wifi.
2 x USB 2.0 host controllers x 2 ports each.
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.
