Benchmark thread. :marseylain::marseylifting::marseykernelpanic:

Not rocket science post your benchmarks.

Ideally we'd have a "battlestation" :marseysoylentgrin: thread but I understand why people would be weird about it :marseyglow:

I used kcbench https://gitlab.com/knurd42/kcbench on Fedora 37 but I assume we have a lot of Windows (:marseysmoothbrain:) users so I don't give a frick.

500 DC to first three posters :marseywholesome:

With my version of GCC it krashes with errors like this one:

subcmd-util.h:56:23: error: pointer may be used after ‘realloc’ [-Werror=use-after-free]

It seems Linux 5.15 and new versions of GCC (12.2.1) don't play nice

Do you have PBO enabled? My 5700g is pretty similar and I get better results with PBO.

I think so since I can boost up to 4.85GHz no problem, what is strange is that it is using acpi-cpufreq as the scaler, few months ago I set the computer to use amd_pstate (it allows the cpu to go to lower frequencies when idling). I'll try to figure out those two things and I'll re-do the benchmark. Also I should definitely have set the scaler to performance for the benchmark :marseybrainlet: as the conservative is a little "lazy" in ramping up the frequency

btw does your little 5700g outperform my 5800x? That would be worrying :marseyitsaover:

Yes but I think it's just 64GB vs 16GB.

Ok, PBO was enabled to "AMD", I changed it to "motherboard" and set the PBO boost to "+20", whatever that means. I got slightly better results but my CPU now boost up to 4.825GHz instead of 4.850GHz and I noticed that it draws 120W maximum instead of ~125W like (I think? I don't remember for certain) it did previously. idk.

On the positive side now it idles at 550MHz like it should. Turns out I forgot to add the kernel parameter to grub's config after I bricked it and had to reset it :marseybigbrain:

Now I'm running 6.1.11-arch1-1 instead of 6.1.10-arch1-1, I changed too many variables at once and now I can't draw any conclusion rip
