Actually, if its to be believed to some devs on GAF from way back, WiiU has 160:8:8 GPU, so that usual 352 GFLOPS figure that's been around (that is for 320 shaders GPU) would be in fact too high for WiiU.
So, what really is safe to say is that PS4 to WiiU gap is at least 6x (given how inefficient VLIW5 (or in best case VLIW4) architecutre of WiiU vs GCN in PS4 is), and maybe much more.

It's not a case of VLIW 5 being inefficient... It's actually not, it's extremely efficient, especially for the amount of transisters.
...Just not in scenario's where Direct X 11+ level effects will be put to full use as you have units going un-used in the array, then it becomes inefficient, but that's also not an issue for a console as Developers know imtimately what the hardware is and can design for it.
Besides. GFLOP's isn't an accurate way to do things, the WiiU could have 100 Petaflops, it still will not beat the PS4, it's not as efficient, other parts of the chip would hinder it, making it useless.
As for the gap... It could even be larger than 6x. GFLOP's isn't an accurate way to gauge performance, using PC benchmarks are, there are effects and use-case scenario's where performance on a VLIW based GPU will simply tank and other scenario's which are generally weak on GPU's of the VLIW era. (Like Tessellation.)
Finding say... A (Assumed for the Wii-U at-best) Radeon 4650/4670/5550 and comparing it to a Radeon 7850 isn't exactly an easy thing to find though. :P Ironically. I have all of those GPU's on hand, save for the 7850.
The Wii U is certainly a gruntier overall console than the PS3/360, but certainly not in the same league as the Xbox One/Playstation 4, the games are proof of that.

Yeah, I can't remember what was that number for VLIW5 efficiency (and too lazy to google), it was AMD's offical paper IIRC, something around 3.7 out of 5 where firing in usual workload, and that was the reason why they moved to VLIW4. Anyway, I was comparing it to GCN and exactly why I said it's at least 6x due to PS4's 1.84TFLOPS are in GCN and (at best) 352GFLOPS of WiiU are VLIW5 (or at best VLIW4).
