lol some people are really nervous by a more powerful XBox.
From what we know Neo is not a full blown Polaris, it might be based on certain things but it's basically just a PS4 GPU x2 overclocked a bit.
A Polaris 10 at 32 CUs is 5.5 TFLOP, so that's obviously not the part Neo is using.
XB2 from the sounds of it will be more like a brand new Polaris 10 (custom), which would enable it to hit 6 TFLOPS without much problem at a reasonable price/power consumption.
Sony is likely hamstrung here by having to stick with something close to the older PS4 architecture, otherwise at 36 CUs they should be getting better performance than just 4 TFLOPS-ish.
