The CPU sets the ceiling of how hard you can push the video card in these benchmarks.
3DMark benchmarks don't benefit much from X3D's 3D-Vcache, so 13/14th gen i9 CPUs can compete very well vs other CPUs.
If the GPU driver isn't causing as much CPU overhead, you shouldn't be seeing less competitive chips like the 5900X (effectively a better binned 5600X in gaming) & 5700X3D in the global top 10 results.

You don't see those older CPUs in the 5080 & 5090 global top 10s because higher-end cards attract more dedicated overclockers who will better tune their CPU & memory.
