which console will be more powerful PS4 Neo or Xboxone 2?

[Soundwave]

Could be a custom order scaled up Polaris 11.

Polaris 11 churns out 2.5 TFLOPS at under 50 watts with 16 CUs.

Bump that up to 40 CUs ... 6.25 TFLOPS at about 120-130 watts.

Or just a vanilla Polaris 10 is already 5.5 TFLOPS at sub-150 watts for $299.99.
