I can go look and get back to you. My claim of over 50% more powerful isn't based on raw specs but with a gameplay scenario running head to head on a Durango vs. PS4 kit. I think in raw spec's is like 28% more powerful or something on paper but Sony's kit running the same scenario was drastically more efficient. With both using x86 architecture now you're really going to see one system shine over the other when multiplatform comparisons happen. Then again, it's all about what developers put at the top of their priority list and how they're tweaked for each system. Being a gameplay guy FPS is always at the top of my list ::shrug::
If you were to see a straight 1:1 port on each system there will be a clear winner in the FPS battle.
