Where can I find a CPU power cost calculator?

Question

Processors

For assembly, an
AMD Ryzen 7 2700X 8 core (Octa Core) CPU with 3.70 GHz, Yes
Enthusiast Octa Core CPU, Yes
for Sockel AM4, 105 W TDP
8x / 16 Threads
Basistakt: 3.70 GHz, (4.30 GHz
16 MB Cache) L3 memory, Unlocked multiplier
Over 9800
Was an option to buy a newer
AMD Ryzen 7 3700X Boxed incl. Wraith Prism Kühler
High End Octa Core CPU, Yes
for Sockel AM4, 65 W TDP
8x / 16 Threads
Basistakt: 3.60 GHz, (4.40 GHz
32 MB L3 cache, Unlocked multiplier
It costs 19,500 already
With relatively identical characteristics, the difference was about 10 thousand. My model has 105 W TDP and the new one has 65 W TDP.
Became interesting. How long does it take me to recoup this difference of 10,000 by paying electricity costs, provided that the PC is turned on for 16 hours a day?

Answer 1

On 16 hours a day and under load 16 hours a day are two different things. If idle, there will be practically no difference. Under load, again, the data is valid only in stock, but not in overclocking. Let's assume that the PC threshes in the sink under load for 16 hours. The difference in power consumption will be 50 watts (why not 40 - because of the losses during the conversion). This is an extra 0.8 kWh per day. Let's take the price tag for electricity 4 rubles. Then we need to save 2500 kWh. This is 3125 days. This is 8.5 years old. Savings on electricity will be noticeable only after 8.5 years. Here, of course, it would be necessary to take into account inflation, etc. but it is already clear that it is pointless to engage in such savings if the PC is not chasing 24/7 doing calculations.
