7700x - 105 watt TDP
7700 - 65 watt
Difference of 40 watts, which is 0.040 kilowatts
Difference in price is $40 (currently as of this deal)
The average cost per kilowatt hour in the US is 0.16 dollars
0.04 kWh/hr x 0.16 dollars/kWh is 0.0064 dollars per hour. 40 dollars divided into 0.0064 dollar chunks is 9375 of those hours.
So if we had this CPU at max load for say 40 hours a week it would be:
$.0064 x 40 hours = $ 0.26 dollars per 40 hour week and $13.52 dollars per 52 week year. That means you hit 60 dollars in about 4.5 years.
And then you have to think do I have my CPU pegged full blast for 40 hours a week?
A lot of people want to wait for the latest x3D, but I doubt any of them will see any actual performance increase unless running at low settings at 1080p with a RTX 4090 (what benchmarks use but no one in the real world would ever do). Right now, you will see no difference between any Zen4 Ryzen CPU so might as well pick one of the cheapest (7600 or 7700 if you want a couple more cores) and wait for the flagship CPUs to depreciate in value. The main reason to pick an expensive CPU for gaming would be to avoid having to buy a new motherboard and ram (which is why 5800x3d was so popular if already have a AM4 board and DDR4; those people are sticking with AM4 and skipping DDR5/AM5 entirely). But with AM5 being a new platform with years of life left in it, you can always just upgrade to your dream CPU later on without having to buy a new motherboard and ram again. If you buy one at the end of AM5 than you can maximize the longevity of your (expensive) AM5 motherboard and ram.
