Fps in CSGO isn’t really so dependent on the GPU as more modern games, so comparing with a different game might be more accurate.

I'm curious, do you know of a study that has proven that single core CPU or other is the bottleneck in CS:GO?

  This is essentially folk wisdom - but I think you can trust the other people in this thread that it's accurate. I doubt anyone has done a scientific study on this, but you could see this for yourself by setting your computer's clock rate lower and re-running the benchmark. I expect that if you have a 4090, you have an Intel or AMD CPU that exposes a core clock multiplier. You could run this benchmark with whatever value it's at, then reduce the modifier by say, half. That should halve your CPU's clock rate, and I'm guessing you'll see the frame rate decline similarly. You can conclude that the game is "CPU bound", then. Even if your GPU was infinitely fast, you have to remember that game developers are not optimizing for the game event loop to run in sub-millisecond times. If the core loop in the game takes under 16ms to run on a common CPU, such as one in a console: that's better than 60hz and the overwhelming majority of video game players will never see a benefit. Some game developers, I see someone in another thread mentioned Doom Eternal, pride themselves on that optimization. With a fast enough CPU and GPU, you could probably reach 1000 FPS on Doom Eternal. A quick search suggests this might have been accomplished with a liquid cooled, this was done with a liquid nitrogen cooled PC with a 6.6GHz CPU: https://www.pcgamer.com/heres-doom-eternal-running-at-1000-fps-on-a-liquid-nitrogen-cooled-pc/ https://www.pcgamer.com/heres-doom-eternal-running-at-1000-f...

  Actually kinda yes, look at AMD’s 3d v cache. There’s a very recent review by the verge on an Asia laptop with the AMD chip, and it does hit like 600-700 fps. CPUs can absolutely make such a difference.

  At that high a framerate, it might even be the transfers to the GPU that are the bottleneck.

  Study, lol. Run the game with uncapped FPS and see your CPU vs GPU usage. Your modern GPU is probably going to be chilling at 30% while your CPU will be pegged in some way (most likely at least one core at 100%).
