I'd say about 350 GFLOPs is about dead on for the Wii U.
100 GFLOPS more than an XBox 360 + double the RAM + triple the eDRAM is a fair sized improvement.
I'd liken it to the first XBox vs. the Playstation 2, similar class of hardware, but there were a handful of XBox games that really looked better than anything on the PS2 and it had double the RAM.



I'd say Halo 4 though looks about as good as any Wii U game. Xenoblade X is probably the only that punches above it.
