Oh, we are finally done comparing work in progress games that have a difference in budget possibly higher than 10x? Lets try not to post unfinished trailers and pictures from Rockstar, they often bullshot up their entire game, if there is a demo video of someone playing on a 360/ps3, we could easily discuss that, otherwises there is little point imo.
Yes 216 GFLOPs with efficiency around 60% (XB1 getting a 66% increase in efficiency over 360 puts it at ~99%) for Wii U this means even if it is 160 shaders (still not confirmeds but it doesn't matter since realistically Wii U isn't going to see many next gen ports anyways) with it's 10% higher clock than Xenos, gives you 176GFLOPs vs 216, the efficiency of Wii U's GPU obviously went up because vliw5 was far superior to the architecture found in Xenos, vliw5 had a ~68% efficiency on PCs with an average of 3.4 shaders being used (the architecture Xenos was based on for PC was lower than Xenos in efficiency, likely because it wasn't programmed for directly) So minimum Wii U's efficiency should be is 80% (meaning 4 out of every 5 shaders are being used) which gives you 141GFLOPs on average at minimum from Wii U, which sounds stupid small until you compare that to 360's which is 130GFLOPs.
Now before you stop reading, DX9 isn't very good for making effects happen, Wii U should always be able to produce better effects than 360's extended DX9 chipset thanks to all the extra effort Xenos has to waste approximating DX10.1/11 effects, which is why stuff like lighting, DoF and tessellation will alwa ys be more abundant on Wii U, because while Xenos might spend 20-30GFLOPs trying to render all those nice effects, Wii U will spend half or less to do the same. DX11 effects btw are mainly from a software standpoint, stuff added like Tessellation software and GPGPU software, could still be done without the software microsoft deemed necessary, and wouldn't be available to PS4 either which is why we always talk about DX11 effects being available on Wii U.
When all is said and done, Wii U's GPU is a lot better than Xenos, especially if you are using a lot of shader effects, in fact the more "next gen" you want a game to look, the faster Wii U's minimum GPU spec closes in on doubling Xenos power.
Edit: Wii U's GPU is probably closer to 90% efficiency, meaning using 4 shaders all the time and the extra larger shader at least half the time. This puts the average usable flop count to ~160 GFLOPs
