(Refer to Watch Dogs for the Wii U)

In that case you can't even run a game like Dragon Age Inquisition with your CPU. The game runs like 18 fps with stuttering on two-threaded processors (I would know my G3258 which I got for emulation until I get a broadwell i5 or i7 barely plays it.) Far Cry 4 needs an injector to get working with two-threaded processors, and you see huge performance gains with an i3 (about 20 fps) and a quad core (about 30 fps.)  Skyrim is a game from 2011. Of course your CPU, is up to par for it. And just because these games run great doesn't mean they aren't being bottlenecked. With an i5 your brother could probably run Shadows of Mordor at 120fps with his GPU. 

Poor comparisons, as the ME ports were not well optimized for the WiiU, much like the poorly optimized AC games at launch or the Batman games. Deus Ex is about the only one that saw even a smidgen of optimization for the WiiU's architecture and capabilities.

Not optimised for Wii U is a popular excuse but do you honestly think a 5670 cant run games like Tropical Freeze, Mario Kart 8 or Smash 900p60fps? Why is Pikmin 3 capped to 30fps, is that poorly optimised? How on earth would running Wind Waker HD at 60fps "break physics" when PS2 remasters run at 1080p60 with bokeh depth of field on the PS3 (Zone of Enders)?Do you honestly think a 5670HD couldnt run those games at 900p60? If you'd ever owned the card you wouldnt say that. 

Because games are different. also, wii u doesn't have an off the shelf gpu and consoles use gpus better, stop using this 5670 example or whatever.

Xenoblade has a bigger area rendered at a given time than skyrim while having much better graphics (polygons, textures,everything else). I don't know what you're trying to say with that "population" comparison, since XCX is full of things on every area. Smash is certainly more demanding than skyrim, with its 1080p 60fps and non blurry/low polygon characters.

Bayonetta 2 IS 60fps, xenoblade is clearly focusing on graphics and draw distance instead of 60fps and Wind Waker HD is 30 fps on wii u because the original game was designed that way. An increase to 60 would probably change the physics. For example, the original kingdom hearts when run on an emulator at 60fps makes objects fall twice as fast, as if doubling the fps increased the gravity.

The fact you aren't accepting is that Wii U games that aren't lazy ports/ports from lower platfroms consistently run at 720p 60fps with much better graphics than ps360 or 1080p 60fps with slightly better graphics than ps360. That's twice the average framerate and three times the average resolution (640p) for those two last gen consoles. Since ps360 had 200 gflops gpus, that easily puts wii u in the range of 600 gflops.

Is the PS4s GPU off the shelf either? No. And yet people compare it to the 7870/7850 all the time. Same applies to the XBox one. The WiiU isn't alien tech and it does not perform the way a 620 gflop card would.

Nothing indicates that the systems GPU runs circles around the 360s Xenos. GPU bound games like trine, most wanted and pikmin all run at 30fps on the system for a reason. The difference between Wii U multiplats and 360 ports are minimal at best. There isn't a single game AAA or indie that runs at 30fps on the 360 and 60fps on Wii U. There isn't any game, indie or AAA that runs at 720p on the 360 and 900p on the Wii U.

Would you call those titles CPU intensive? No. Lazy ports? Intellectually dishonest. Were looking at a 40 to 60% processing power boost over the 360. 336 to 384 GFLOPs is  reasonable and explains all the 720p60 games. Anything else is wishful thinking.

The RAM helps but if I was to describe a powergap I'd the the 360 is a Nintendo 64 and the Wii U is a Nintendo 64 with the memory expansion pack.

Because games are different. also, wii u doesn't have an off the shelf gpu and consoles use gpus better, stop using this 5670 example or whatever.

Actually the PS4's GPU is a standard pitcairn with a few modifications (lower clockspeed, fewer shading units, etc) , but nothing like what was discovered in the analysis of the Wii U's GPU (which doesn't look very similar to an r700 that it was supposed to be based off of.) I don't know the details of the Xbone's hardware, so I won't comment on it. 

At the very conservative estimates, the Wii U's GPU is about 1.5 times (or 50%) Xenos in raw power. If we consider the extra memory bandwidth the Wii U has over the 360, then that is an even more significant difference.

Pseudoscience. What proof do you have for that claim?

Frame-rates tend to be locked. Let's say that the game runs 31 fps unlocked on a Xenos, but 45 fps on the Wii U (average) unlocked. That represents a 1.5 times difference, which if the port wasn't a straight port can go into other features (like anti-aliasing or geometry detail.) Still, they'll lock the game to 30 fps because of monitor and television standards, and dedicating resources to vsync won't be worth it.

Made up figures to suit your argument. Give actual framerates from actual games

Having said that, many 360 games run sub-HD and sub-30 fps while an overwhelming majority of games run 720p on the Wii U with a locked 30 fps.

Please list multiplats that are sub 720p on the 360 and full 720p on the Wii U

Furthermore, we see games like SSBB run at 1080p 60 fps on the Wii U.

Several Nintendo fans on VGChartz itself admit that Smash U looks like Smash Brawl running in Dolphin. This is the same game that runs on a 3DS. The game isnt pushing high poly models, stages or fancy effects by any stretch of the imagination. The PS3 has several 1080p60 games as well. Apart from Smash what games run at 1080p60?

I have a hard time believing the 360 would keep up with this, for the sole reason of memory bandwidth alone. Most of the 360's 1080p games were much simpler than SSBB. 

Examples of how Smash is so complex? Feel free to use screenshots. Figures of the Wii Us "super bandwidth" compared to the 360 would also be nice.

Notice how first party, exclusive games, which take advantage of hardware that is unique to the Wii U tend to outperform multiplats. How can you say it is intellectually dishonest to call these multiplats poor ports in reflection of that? 

Thats true for exclusives on every system, see PS3, PS4, X1 and every console known to man.

Your statement of the 360 is a N64 and Wii U is an N64 with a memory expansion is ridiculous.

How so. Given the enhancements the memory pack offered to the vanilla M64 the analogy fits perfectly. If anything, the Wii U doesnt even offer comparable gains.

Even if we ignore raw power, the Wii U's GPU supports more modern features than the 360's, including things like hardware tesselation.

So what? The 5670HD also had Direct X11 featues bu DX10 cards like the 4870, 4850 and 4770 are still stronger. Those features are only as good as the power backing them up. The 360 also has a hardware tesselator, it was used in all Forza gamnes, which were 720p60 with 4-2x MSAA. Somethng still absent on the Wii U.

This is evident in the effects found in Wii U games. Additionally, the GPU is at the very low estimate 50% faster, and the ram amount and bandwidth is greatly excessive. The CPU is a bottleneck of course, and that is the main reason why multiplats don't run that great, but also not the only reason. 

Source for "greatly excessive" bandwidth please?
