*Speculation below*
When all the above blocks of the GPU are accounted for, there is still 30% of the Wii GPU die unknown and open for speculation. This leaves what many have assumed to be “Nintendo Customizations” to the GPU to meet their needs of power consumption while still getting the desired “Next Gen” effect, similar to the techniques used in designing the Gamecube. Fixed-Function effects that would be used in just about all Next Gen games like Lighting and Tessellation could all be embedded on the hardware without the need to be programmed. This would have a big effect on seemingly getting more with less. The Wii U GPU could perform the same or maybe a little better than the AMD e6760 (which was speculated to be the Wii U GPU) for example even though that GPU contains 480 SPUs, since the *speculated* Fixed-Functions of the Wii GPU would be able to work in tandem with the 320 SPUs it already has. The benefits of a design like this would have helped Nintendo make a more cost effective and smaller GPU, while still getting most of the effects of the “Big Boys” that are about to be revealed in the coming months. So again, this is a Nintendo console that doesn’t simply have an AMD Radeon R700 type GPU inside, but a heavily customized and well thought out design that can’t so easily be put on a spec sheet. Just like the Gamecube in 2001, the Wii U GPU will be deceptively feature rich and have much better performance than what any numbers will tell you. The only unfortunate part of the whole development side is that Nintendo failed to give developers enough information on everything that the Wii U GPU could do in the early stages of development and it showed in many of those ports at launch. Nintendo has already confirmed this somewhat in the latest earnings reports and interviews, so in the coming year I’m expecting games that show what the system is truly capable of doing not only graphically but in a gameplay sense as well. Look for Retro Studios and Nintendo themselves to set a good example of this later in the year (like they always need to do with new hardware).

So Nintendo failed to give developers enough information of what the Wii U GPU is capable of. This just tells me that Nintendo dev tools are not that great at the moment. How much performance can they squeeze out of this weak GPU once the dev tools are optimised only time will tell?
I say weak because of the following two points
1) The GPU is running on an older AMD GPU architected (VLIW5) fabricated on 40nm
2) The whole systems consumes 30-40 watts of power
No amount of fixed function hardware will increase its performance to match the PS4 or xbox720....Not unless Nintendo is so how breaking the laws of Physics.
The fact that the whole Wii U system consumes about 30-40 watts of power, the GPU is fabricated on a 40nm node which is less power efficient than 28nm, and that it's an older GPU architecture rated with a DX10.1 feature set, simply means the Wii U will not be cable of much more than the PS3/360, let alone being anywhere near the PS4 or xbox720.
People need to keep in mind that power consumption, fabrication nodes, and architecture will gives an understanding of what these consoles can be cable of. As point of reference, both PS4 and X720 have an estimated power consumption floating around 150 watts, Aiming for 28nm fabrication, an AMD GCN architecture with DX11.1 feature set.
So given all the information we have, I am still surprised people still hold this idea that the Wii U somehow has this hidden graphics capabilities. Look don't get me wrong, people who are Nintendo fans subconsciously want the Wii U to be graphically capable, I completely agree with their mentality. But reality has to be faced, Nintendo bailed out that arms race with the Wii, and the Wii U is no different. Now I'm not saying that the Wii U won' be able to achieve nice looking games with it's hardware cuz we've seen some amazing games come from both PS3 and x360 hardware it's just that they won't match what the PS4 and x720 are aiming for.
I suppose if Nintendo fans can't live with Nintendo’s direction, then perhaps it's time to move on, otherwise accept Nintendo’s direction and enjoy the games and franchises they have, or like some here, partner the Wii U with a PC, PS4, or X720. This way it's a win-win situation.
Welp that's my 2 cents.
