Intel i5-12500 vs i5-13500 Unraid (lemmy.world)

Kind of a dumb question but I’m genuinely curious: is this a worthwhile upgrade? I run a server with a single vm and a few dozen docker containers. I’m intrigued by performance and efficiency cores and whether there would be a noticeable effect on both energy efficiency and performance vs the 12th gen. I’ve looked at the cpu benchmark comparison and see the numbers and there looks like a big increase in performance with little downside other than the cost of doing it. Any input is appreciated.

I'm always look at ongoing costs rather than upfront and mostly thats the TDP, which is exactly the same. So I would agree with your sentiment. The major cost is performing it.

Single thread has a small increase 5% or so, but you have double the amount of threads. So your two dozen (24) docker containers could have a thread per container! Thid could benefit you a lot if you were running anywhere near 100% or have long running multithread jobs.

If I had the disposable money and I thought I could sell the 12th gen CPU then maybe. But i'm still rocking some old E3-12xx v3 Xeons which probably costs me more per year than what you will pay to upgrade!

How performant are the efficiency cores and does Linux/docker make good use of them? I'm skeptical of the new variant of performance/efficiency core make up. 24 cores is great, but aren't most of them the equivalent to an intel Atom?

Bah! I totally forgot that they have the new "efficiency" cores...

Performance Cores: 6 Cores, 12 Threads, 2.5 GHz Base, 4.8 GHz Turbo
Efficient Cores: 8 Cores, 8 Threads, 1.8 GHz Base, 3.5 GHz Turbo

Hmmm, I'd still say its totally worth it because the 12500 only has 6 core (12 threads) total. You are getting 8 extra core/threads.

Linux/docker/anyOS will make use of 8 extra cores regardless of the workload. Sure they might not be as performent on the lower end but a process running 12 threads vs a process running 20 threads will always be more performant.
