When they say CachyOS is mostly for newer machines...what's "newer" (lemmy.ca)

Been Manjaro for years and years. Latest update (due to my own screw-up...not the distro's fault) shit the bed and corrupted my timeshift backups (again...my fault...not the distro)

Wasn't too concerned because a) I keep everything on a backup drive, and b) I'm a big believer that every computer needs to be refreshed with a new install every few years anyway.

But now that that time is upon me, I got to thinking about maybe giving CachyOS a shot for the "performance improvements". But my desktop is coming up on 9 years old (AMD A10 processor). Would it even be worth it to try Cachy in that instance, or would the performance difference between that and Manjaro be negligible on that particular processor?

CachyOS will work on older hardware as well. There are four repositories for x86-64 v1, v2, v3, and v4. If you have newer hardware, the v3 or v4 packages will theoretically give you better performance. That is probably what you are talking about.

That said, the v1 repos will work on x86-64 machines going back to 2003. Not exactly bleeding edge.

The only thing that I have noticed is that packages are not all in sync between repos with v1 lagging behind v3. For example, I think Cachy is already on the 6.18 kernel but the v1 repos still only have 6.17. I have seen svt-av1 lag as well.

I am not a CachyOS user so apologies if any of my info is dated.

I will never say anything bad about EndeavourOS.

Who says CachyOS is mostly for newer machines?? I don't know why anyone would make such a claim. At least on their website, no such claim can be found. The official system requirements are listed at https://wiki.cachyos.org/installation/installation_prepare/ , you can switch between minimum and recommended set.

I was on Manjaro before too and can recommend the switch to EndeavourOS too.

Optimized Repositories for Cachy only have any real effect on newer processors (x86-64-v3 and up). Of course I can still use it on an older machine, but I was asking if my processor (AMD A10 "kaveri") would be new enough to take advantage of those optimized repositories. (my research so far says no....AMD didn't add v3 until the next years processors in 2015)

You're link actually answered my question, though. So thanks! Don't know why when I searched it wasn't finding that page for myself. Maybe my Google-fu needs some retraining.

Well, no need to websearch. Just go to the website and look for any official links, such as the wiki. As for the optimized packages, I found this on their website:

CachyOS does compile packages with the x86-64-v3, x86-64-v4 and Zen4 instruction set and LTO to provide a higher performance. Core packages also get PGO or BOLT optimization.

So the listed CPUs in the requirements list should take advantage of this I guess. And my assumption is, that these CPUs are required to run the packages at all. Maybe that's where the "newer machines" is meant with.

i run Cachyos KDE on a 2013 Xeon e5-2667 v2 and a GTX 1070 ti. no problems. best distro I've used.

What's interesting about CachyOS is you can install mods on any Arch you like. I have EndeavourOS (best Arch distro imho) and recently installed the CachyOS mods and it works great. Check out the following video for an easy guide.

One of the advantages of CachyOS ist the compilation with the x86-64-v3, x86-64-v4 and Zen4 instruction set. If your cpu does not support any of these sets your theoretical performance gains will be smaller since you do not get the advantage of these tailored compilations. The other things Cachy does like increased swappiness etc. should still work. Check the wiki to see if your cpu supports these sets.

I don’t have an answer to your question but I use and love EndeavourOS which is pretty similar

[-] Adderbox76@lemmy.ca 3 points 5 days ago

That's another option as well. It's between Endeavour, Cachy, or sticking with Manjaro.

Usually my primary consideration is community size and/or team size. Too many linux distributions seem great, but have low support and eventually just vanish, so I always try to stick to the "bigger boys". Not saying Endeavour is that, but once upon a time it was the new guy on the block and that's why I've waited to consider it. Same with Cachy. I wait to see if they've proven their staying power before considering them.

I use a 14 year old Asus with 8 GB ram, used it with manjaro KDE for a period of 4 years .Now ive been using cachy KDE for about a year ,
no problems here , startup about 14 sec on a SSD

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
