Factual PS4 Hardware Advantages: +6 CUs, +560 GFlops (44% greater), +16 ROPs, +6 ACEs/CQs, better GPGPU support, better performing CPU, and faster unified memory. PS4 OS may also have less overhead or reserves.

Both Sony and MS have world class coders that will extract every bit of performance out of their consoles with their drivers/APIs/SDKs. The difference is PS4 simply has more powerful hardware to work with, so it will always stay ahead in graphics performance.

Every console has a power budget that can be put towards resolution, framerate, or visual effects. PS4 has a higher total budget than Xbox. Therefore Forza 5 would run better on PS4, and Driveclub would run worse on Xbox.

PS4 will have better performing games for the entire generation as it has more powerful hardware, you can’t overcome a hardware gap with better drivers/SDKs. Any game running on Xbox One can be run with better framerate/resolution/visual effects on PS4.

Even if Xbox had a far more powerful CPU and 10000GB of 10000 GB/s memory, it’s ability to render graphics is STILL limited by the weaker GPU. There’s no getting around the weaker GPU, there’s no free lunch.

DDR3+ESRAM is still a size and bandwidth bottleneck and difficult to code for. The DMA registers help transfer data between DDR3 and ESRAM, they aren’t super special sauce.

If they’re both running at the same resolution the Xbox version will have lower framerate and/or visual effects, or the PS4 hardware isn’t being pushed.

Xbox has memory size and bandwidth bottlenecks, weak GPU and GPGPU, only 16 ROPs, and OS virtualization overhead that all degrade gaming performance. Take your pick.
