Which Kernel should I use

[SGS]

If you posted your garuda-inxi* now (and later, with new CPU,) you’d get, maybe better responses.

*The template asks

Most people use what works, then install another kernel and boot it. Don’t delete the one that works and test it, and so on and so forth.
IIRC right, there is not much difference in normal life between kernels.

For my AMD Ryzen 9 CPU’s I use the linux-amd-znver3

The difference between all your benchmarks is ~1%. None of it is significant. This is my experience with almost every kernel I have ever tried. On my hardware there isn't a material performance difference in general use. In the end benchmarks are only useful if they match your workloads nearly identically. Benchmarks also don't measure things like responsiveness.
