They had a thread on the inside development story of Wii U on the Wii U Daily forums and I found a pretty interesting post from Quinton McLeod
here it is below
"This was an interesting read, but toward the end, I took some issue with some of the information presented.
Sorry, but I have to call it... This is BS.
55nm process? No. It's a 45nm process. 10nm makes a pretty big difference.

He then expects us to believe that CPU in the PS4 is just a 28nm process, except he's only talking about 1 CPU module. Lets not forget that the Jaguar line of CPUs are only quad core. Sony elected to make an 8 core CPU. That makes the CPU much bigger. Not only that, but it's an APU with the full 7870 silicon, thus making it a BEHEMOTH!
The extra 100w (137 watts total) is probably due majorily to the TDP on the GPU itself.

The Wii U's wattage is 33 watts max.

So what does wattage have to do with performance? NOTHING! Nothing at all. Intel is able to squeeze more performance per watt than any of AMD's processors. AMD's FX series of processors are a joke compared to the i7. Not only do they run hotter, but they are less efficient and therefore are much slower. Wattage means absolutely nothing.
Then he says the GPGPU's shader model is incompatible to shader 4.0. Really?
First off, "Shader Model 4" is Direct X. Shader Model 5 is backward compatible to 4.0. There is no Shader Model 6. So, what the hell is he talking about?

Also, someone on another forum stated that the Wii U does support Shader Model 5.0:

I wouldn't trust a word this guy has to say based on some of the information he's provided. Chances are, this is an EA developer. I have no doubt about it."
