For what it's worth, you may be pleasantly surprised by the performance if you upgrade. I went from an Ivy Bridge processor to a Zen 3 processor, and I found that there were a lot of real world scenarios which got noticably faster. For example, AI turns in a late game Civ 6 map went from 30s to 15s. I can't promise you'll see good results, but it's worth considering.

What factors would be compelling to upgrade for?

Just curious, since perf alone doesn’t seem to be the factor.
