Benchmark the hardware doing 3D rendering. Which is a pretty niche use case for most people that doesn’t correlate well with more common cpu-intensive tasks like gaming or video editing.
Video editing is just as niche as 3d rendering. But really neither are actually that niche, see for example https://www.blender.org/news/blender-by-the-numbers-2020/
And to put those blender numbers in comparison https://prodesigntools.com/number-of-creative-cloud-subscrib...
Geekbench is an even worse benchmark than cinebench. It's extremely heavily influenced by the underlying OS rather than the hardware being compared.
Cinebench 1T and mT at least actually benchmark the hardware.
