Difference between PS4 and XB1 CPU is so small this wouldn't happen though. |
The Xbox One has 9.375% CPU clock advantage over the regular Playstation 4.
The eSRAM can also function as an L4 cache to bolster CPU performance, increasing that performance divide.
The Xbox One's DDR3 memory also has a slight latency advantage over GDDR5 which also benefits CPU performance. (I can do the math on this if you want me to?)
In a best-case scenario you could be looking at upwards of 15% more CPU performance for the Xbox One.
If you paid attention to various Digital Foundry videos you can see the Xbox One will sometimes have higher minimum framerates than the Playstation 4 in a fair few multiplatform games, especially when there are allot of entities on-screen. This is most likely thanks to the CPU.
On allot of these games that have Dynamic resolutions... When your framerate takes a hit, then your resolution drops, in the Xbox One's case, at a high resolution it's most certainly GPU bound, whilst at a low resolution it's CPU bound, thus it's not far-fetched to assume that in CPU-bound scenario's (And if there is no GPU-limits) the Xbox One should in theory be capable of a higher resolution than the Playstation 4 in those instances. - If all things are equal of course.
With that said, you are mostly right, this is unlikely to happen due to developers targeting for the hardware specifically and knowing what they are working with, but on the PC, if you pair up a weak CPU and a strong GPU, the CPU can and will hold your framerates back, especially minimum framerates.
