There is a Wii U early target specs sheet that was put out today which people 'in the know' are saying is legit if anyone is interested.
Doesn't really have any specifics on GPU performance though.

- 1.5GB RAM
- 32MB high-bandwidth eDRAM
- Built-in b/g/n Wi-Fi
- 4 USB 2.0 ports
- An SD-card reader
More detailed specs at the link.
