So PS4 GPU performance is double X1.

I expect the PS4 version of Unity to run smoother if both X1 and PS4 are 900p then.

D.I.D.

The GPU is better, and these are theoretical limits of performance that you'll never see in a game.

Data needs to be delivered to and from the memory, and in both machines the GPU and CPU share that bandwidth. If the GPU was the only thing working then the PS4 would destroy the XBO, but that's not what you'll see during a game. With the CPU and GPU working simultaneously, the PS4 still comes out on top but not by this gigantic margin.
