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...
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.
The extra cores do sound sweet huh? I’m gonna set up a price watch. Will report back if I do it.
