That doesn't make it any less capable. Measuring performance requires more than looking at raw floating point power ...

wii u estimates start at 176 gflops and go up to 352 gflops, however the fact is the wii u gpu likely has a wii gpu integrated into it and this gpu may run at higher speeds in wii u mode to generate the gamepad screen when independent of the main screen. At best it probably adds 30 gflops performance to the main gflops performance of the wii u. The performance level we have seen from wii u makes it highly likely the performance is at the lower level 176gflops. However architecture differences means this will perform probably 30% plus minimum over the older architecture of the 360 gpu. Roughly speaking the wii u gpu is about the same performance level as 360/PS3 but has an enhanced feature set and has 32MB of ultra fast embedded memory. So its is bottleneck free almost. However still it performs below 360 and PS3 on most ocassions due to a slow CPU and low main memory bandwidth.

LIkely wii u architecture is something like a mobile Radion 6400M. Mobility architecture is extremely likely due to less heat issues even when fabricated at a low cost 40nm process as used in the wii u.

For the wii u to take so little power and produce so little heat that only needs a small fan it has to be a fairly low performance gpu. Not only that but you have to factor in the low bandwidth memory chips used which are less than 360 and PS3. It would be pointless fitting a higher performance gpu with such limited memory bandwidth. Lets not forget in the wii u that memory bandwidth has to be shared by both gpu and cpu. The 32MB of embedded memory certainly helps but its clear there would be huge restrictions on a more powerful gpu.

• Engine clock speed: 480-800 MHz (wii u gpu is at about 550mhz so 176 gflops)
• Processing power (single precision): 153-256 GigaFLOPS
• Polygon throughput: 120-200M polygons/sec
• Data fetch rate (32-bit): 15.36-25.6 billion fetches/sec
• Texel fill rate (bilinear filtered): 3.84-6.4 Gigatexels/sec
• Pixel fill rate: 1.92-3.2 Gigapixels/sec

• Memory bandwidth: 25.6 GB/sec (GDDR5) or 12.8-14.4 GB/sec (DDR3)

12.8GB/s is the DDR3 memory speed fitted to the wii u

Then how is Nintendo able to create something like X or Bayonetta 2?  Those games look significantly better than anything on the 360/ps3.

So you think the Wii U is weaker than PS360?

That is NOT the question imposed though is it?

No, it's not. What was your post suggesting then?

just because you say it doesn't make it true.

what did I say?  what isn't true?

about x and bayonetta 2 looking better then the best 360/ps3 games i happen to think those games are not even close to looking like the best 360/ps3 games.
