The Xone CPU clocks 9% faster than the basically identical PS4 CPU. And right now it seems that the Xbox OS is slightly more CPU-efficient. The latter might change though.
Now for DX12 in very short: It's more efficient. THough probably not that more efficient than the Xbox API is right now in every part. One very important thing is it actually is more CPU efficient. It's also more efficient on the GPU side as it seems but again, some things benefit more than others.
So i wouldn't actually expect miracles.
Another thing is that Sony can otpimize their system as well. And they will, sooner or later.
