Looking through I see that some specs in the second post haven't been updated. The wii u has at least 35mb of built in memory for the gpu. As in addition to the 32MB it has to have the 2MB frame buffer and 1MB texture cache for wii compatibility mode.
If you are stating 176-352 gflops you should also state 160-320 stream processors.
Is the wii u gpu 550mhz or 600mhz? I thought ps3 was 550mhz and wii u gpu 600mhz. Not checked though.
