Wii U .. 5x 360
Xbox3 .. 12x 360
PS4 .. 10x 360
I agree. When you don't the variable(s) it makes it tough to properly comprehend it. I prefer to learn about the hardware and project the level of output it's capable of.
What I find funny about those numbers, is that the xbox3(@2.41x Wii U) would have nearly exactly the amount of power required to output 1080p(~2.25x) of what the Wii U offers at 720p.
The numbers are pointless though, I can't believe we are still talking about them, it would mean that the Wii U is @ 1.2 Tflops (GPU) and the Xbox3 has all the same features with 2.9Tflops (GPU)
That is comparable to these AMD cards:
Wii U: HD7770
TDP: 80watt (for full card with memory)
Xbox3: HD7950
TDP: 180watt (for full card with memory, no die shrink ready until 2015)
Those numbers are a bit outrageous for the Xbox though. Luckily both cards can cut probably 30% of the TDP numbers thanks to not needing compute units/memory;
leaving the Wii U's GPU under 60 watt TDP and Xbox 3's GPU under 130 watts.
That doesn't take into account the rest of the hardware, or the fact that Xbox to Xbox360 was only a 6x GPU increase, Xbox3 is expected to be twice the hardware jump of those two systems, that is a bit crazy.
I see the GPU break down being more like this:
Wii U: 768 Gflops - 1200 Gflops
PS4: 1000 Gflops - 1500 Gflops (possible 2nd GPU for computing IE physics)
Xbox3: 1200 Gflops - 1800 Gflops (possible 2nd GPU for computing IE physics)
