Who plays games at 360p or 720p? Pretty much no one. So it's presenting an extreme outlier of no relevance to my use case or indeed any normal gaming use case as conclusive. Disingenuous as I said.
That is not an answer to my question.
As with CPU's GPU's are also limited in performance, they have a performance ceiling at a given resolution.
If a CPU is not powerful enough to drive a given GPU in a given game the the performance you get is limited by the CPU, if the CPU is fast enough or faster then the performance you're getting is limited by the GPU.
So when you're testing CPU performance and all the CPU's you test are fast enough to drive that GPU to its fullest extent then all those CPU's are good enough for you, but if you want to know which CPU is actually faster, or to put it another way if you want to know which CPU has the most headroom you have to use a faster GPU, if you don't have one what you can do is reduce the resolution in the game, in doing that you're moving the performance bottleneck away from the GPU, you do that until you find where your Frame Rates are no longer increasing, that is the point where you CPU can no longer keep up with the GPU, whatever the difference then is between those CPU's, IE the one with the higher frame rates is the more powerful CPU, the one with the most headroom.
This is not a new thing, its been done for decades to find the highest performant CPU.
Its a bit like those people who say "There is no point in having a fast car because you can't drive at more than 70 MPH" That isn't the point of owning a fast car, you would still like a fast car because its fast, even if you never drive it at more than 70.
