If it has a newer CPU/GPU it will boost performance, that is inevitable. The question is, how much? If an X1 game get's 56 FPS, the XB1 S may (hypothetically speaking) get 57-58FPS - hardly anything to write home about :) You'll get more benefit from the 4K upscalling and HDR. It's not as if this console will suddenly make everything 1080P/60FPS haha
