I’m looking at some old Intel and Pentium CPUs that are in a NUC. Are cores and max clock speed the only things that matter? Would a Pentium be good enough to run Immich? I have a i7-4790, and the NUCs I’m looking at range from a Pentium J5005 to a i3-1115G4. I do run Docker, does that affect anything?
CPUbenchmark.net is the best way to compare 2 CPUs.
Directly comparing cores and speed is only useful across the same architecture, comparing brands and different generations should only be done via benchmarks.
I can’t provide any feedback about if those CPUs are enough for immich as I do not use it.
Look at generation first. Look at ram speed, clock speed, number of cores and cache after checking the generation
If you just do a search for <cpu1 model> vs <cpu2 model> often times you get pointed to sites that can do that comparison for you.
For example searching for: J5005 vs i3-1115G4
gave me several links one of which was Intel Core i3-1115G4 vs Pentium Silver J5005 - UserBenchmark
There were several other sites with similar headers.
As for best one for Docker, that too you can search. Specially if you use something like perplexity.ai and you ask which of those two is better for docker it gives you a nice comparison along with which areas one is better than the other as it pertains to using Docker. Suspect you can get similar good info from using any Large Language Models (LLM) like ChatGPT or Claude.ai (both of which have free plans)
I would avoid the userbenchmark site, the owners are heavily biased against AMD, so their benchmarks cannot be trusted
I think more important is compute per watt and idle power consumption than raw max compute power.
For desktop CPUs… Higher number = better. That’s it. i5 > i3 > pentium, 11xxxx > 10xxxx > 9xxx… etc. For laptop CPUs… Good luck
