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?

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.

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.

Maybe add Geekbench, but only within the same architecture. Tests between different architectures are not comparable.
