How do I determine if a CPU is better than another one?
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?
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.
This is my go-to for a first look. You might want to see if the CPUs also support special features like encoding/decoding acceleration, because doing stuff like that in hardware is much, much faster than doing it in software with regular instruction pipelines.
