With any discussion about the latte fabrication you have to bear in mind the huge amount of stuff included in the latte, not only is a huge part the edram but there is also the arm cpu, audio dsp, 1MB wii u texture memory, 2MB wiii frame buffer, wii gpu, sections designed for high speed compression of the wii u gpu frame buffer and downscaled to fit in the wii gpu frame buffer. There is a huge amount of additional stuff.
The 176 gflops figure is completely realistic, not only does it fit in with the power consumption figures but it fits in with how the wii u is actually performing. Let's not forget the generational difference between 360/PS3 gpu's and the later radeon's is quite significant in performance.
If the latte really is 352 gflops and the architecture is much improved plus you have 32MB of high speed edram then what the hell is going wrong that the wii u that it is struggling to outperform 360/PS3 graphically? The figure of 176 gflops makes total sense, it simply works with all the information we have. If the latte really is 352 gflops then something has gone horribly wrong in the design of the wii u that is creating major issues. I don't believe this. I believe Nintendo have a designed a console at the absolute minimum price to merely match current gen performance overall. However as a wii u owner I'm more than happy to be proved wrong but the evidence surely dictates that of the possible range of gflops performance 176-352 gflops where once we were clinging on to believing it was 352 gflops infact the lower figure is much more realistic.
I guess an alternative view is that CPU is so weak that the compute functionality of the radeon gpu is being utilised for practically every game and compromising graphic output. I don't believe this myself. I also don't believe the wii u console is hard to develop for, I believe the complete opposite is true and I don't believe all developers are being lazy on wii u either.
Ultimately I believe the wii u is a low performance console designed to a specification for good quality cartoon graphics for Nintendo games and a huge profit for Nintendo and its shareholders (if it sold well). A continuation of their 'withered technology' philosophy that was so successful for gameboy, wii etc.
