CPU performance difference

Hello,

I ran geekbench under Arch and Fedora and I noticed that the score is a lot lower under Fedora, how can that be?

Were the tests ran on similar kernel versions and power management settings, as both can have an impact on overall performance. Even tweaks made to the kernels for different optimization needs can also affect performance.

Kernel and power management were identical, I can’t say the kernel parameters because I don’t know them from fedora.
I would have expected a few points, but over 2500?

Yeah, kernel paramters probably wouldn’t cause that wild of a swing. It definitely seems like multiple things (including possible throttle-happy power management settings) compounding to cause that large of a difference.

I’m not sure what profiling tools or extra logging could be used to probe what’s going on, as that’s getting a bit outside of my level of stuff.

Interesting, since I’ve been on Fedora 42 it seems to have improved:

Your scores seem circumstantial, since both the Fedora and Arch results are sometimes higher and sometimes lower than the other. It’s certainly not the case that the Arch scores are consistently higher.

Also the Vulkan tests you did resulted in a much higher score on Fedora than on Arch:
