AMD is getting almost 30% better performance at 287 watts than Intel at 380 watts (Intel W-3175X in the review). If you're actually using all 32 cores all the time, you're saving TONS of money overall. Not only are you doing 30% more work, but at 25% less power.
Even if you left it on 24/7, it would take you a year and a half to make up the difference in price between the $2000 AMD and the $3000 Intel. If we assume both chips have identical performance, the Intel would cost $4350 to run over 5 years vs $3480 for the AMD (assuming 24/7 at all cores). The total cost of ownership for that Intel chip over 5 years seems to be around 2x that of the AMD chip.
I'd note we've been talking about 32 cores 24/7. If you're using 4 cores and 8 threads, you will be using half the power (about 140 watts). If your system is idling, it's using a bit less than 50 watts.
Let's say you leave your system on 24/7. You work 8 hours, play 4 hours (4 cores, 8 threads constantly running), and it idles the other 12 hours. We'll assume that you somehow max all cores for your entire workday and max 4 cores during play. You'd be well under half that price per month.
Change all-out time to a more reasonable, but still strenuous 4 hours with 8 moderate hours and shutting off your computer at night will get you down to less than $20 per month.
