Can I replace all Arch packages with CachyOS packages?

[Debian_SuperUser]

Found out about CachyOS and it is also becoming more popular. I am mostly interested in its repository because it has packages compiled with newer instruction sets. But I tried out Chromium (x86_64_v3 is supported on my system), and on Speedometer 3.1 I didn't see much noticeable improvement. Compared that to the Thorium project, that scores quite a bit higher but it lacks updates. Is there any noticeable difference between all the packages? The CachyOS kernel is available on the AUR.

Is it a good idea to replace Arch repos with CachyOS repos without actually installing CachyOS?

I have not tried it. but they should be quite compatible. Though Cachyos developed packages may not work on Arch.

Yes you can.

I have tried it. My personal opinion is from a user perspective you aren't going to notice much of a difference but it might depend on your hardware. I didn't see a performance gain or feel that my system was snappier or more responsive than my normal Arch installation. Just try it and see for yourself, just make sure you create a snapshot from before if you want to go back to a normal Arch system.

@f33dm3bits Have you benchmarked the kernel at least? For me that's the only major package besides my browser and my terminal.

No real benchmarks, I just compared the average fps I got and there wasn't really any difference in that. I've also used Arch Linux different kernels: linux, linux-zen, linux-lts and linux-cachy, I never found there to be any real difference in how my gaming experience and the the fps I got. My personal view is, if you can't notice the difference it's not worth it. But that's why I said you should try install CachyOS repos on your system so that you can experience it yourself. It could be that you have a different experience with different hardware, I'm just sharing what my experience has been with using CachyOS repos and packages, as well as the same thing with having tried different kernels.

@f33dm3bits What processor do you have? One that even supports AVX-512?

@Debian_SuperUser I have a "Ryzen 9 7900X 12-Core", it supports "AVX512".
