Wii U GPU Die Image! Chipworks is AWESOME!

VLIW4 is found in very few GPUs - 69xx and current APUs - AMD moved to GCN after 69xx series for their cards, and new APUs will also have GCN inside. HD 2xxx/3xxx (R600), HD4xxx (R700), HD5xxx (Evergreen) and HD6xxx (Northern Islands) minus HD69xx are all VLIW5. Since Nintendo decided to use older desings (R700 is usually believed to serve as base, though there is everything, even R600 as of lately, as speculation), it is most likely that it is VLIW5 inside.

I can't really pretend to understand Nintendo's design philosophy, but as BlueFalcon mentioned several times, it is really unfortunate they haven't opted for some AMD APU instead of this design - they would get both better CPU and GPU component, and Dolphin is excellent example they could've made software Wii emulator for backward compatibility.

Well, as zarx said, the Xenos had an R500 architecture, but with R600 shaders. Is there any reason (either theoretical or in terms of the die image) why the Wii U couldn't have R600/R700 architecture, but VLIW4 or GCN shaders?
