Interesting, I run a small cluster of 4 mini pcs (22 cores total). I think it should be comparable to the aforementioned EPYC. Power load is a rounding error compared to appliances like electric iron at 1700W, etc. The impact on electrical bill is minimal as well. Idle power draw is about 5W per server, which translates to ~80 cents a month. Frankly my monitor uses more power on average than the rest of the homelab.
