The GPU would have faced significant customization over the past 3 to 4 years, and would be manufactured using a much newer and smaller process, so what we know about the stock PC GPUs may not hold true for the GPU in the Wii U.

yes but customisations don't magically increase performance per watt and Nintendo won't go below 40nm which is just 1 step from the 55nm original. The customisation will likely be less shaders and some eDRAM to get good performance at an acceptable wattage.

Actually, customizations could change performance per watt pretty substantially ...

Companies like ATI and nVidia are able to release a new generation of GPUs (roughly) every year because their chips are designed in a modular fashion, and the work from existing chip designs. Many of the design changes that were made for the Radeon 5xxx, 6xxx, 7xxx and are being made on the 8xxx series of processors could be back-ported to the chip ATI is working on for Nintendo; which could translate into significant improvements in processing power per watt.

By the time this chip is released it could have one of the highest performances per-watt of any GPU ATI makes; I'm not saying it is, but we simply don't know and can't assume based on a 4 year old version of it that was released for the PC.
