Not sure. gpu+cpu:
PS4: ~1.95/2TFlop (32ROPs, 1152 stream processors,
Xbone: 1.4TFlop (only 16 ROPs on gpu so 720p will be very common, 768 stream processors)
WiiU: estimates range from 300 to 600TFlop (8Rops, 320 stream processors)
There are as many ROPs and stream processors on the PS4 vs Xbone gap as the Xbone vs WiiU gap. The gap between PS4 and Xbone is ~500Gflop, Wii vs Xbone can be 800Gflop at minimum |
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.

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