Power Consumption

Next, a look at the power consumption numbers across the six tested games.

Reminder:

• Core i9-12900KS Base TDP: 150W
• Core i7-13700K Base TDP: 125W (20% lower)

• Across my six benchmarks, the Core i9-12900KS drew 113.1 watts on average, while the Core i7-13700K used 105.6 watts. This makes the Core i7-13700K 7.1% more power-efficient in 1080P gaming.
• The CPU with the lower base TDP wins, though not by a significant margin.

Thermal Performance

The Core i7-13700K was the more power-efficient CPU, but is it also more thermally efficient? Let’s see. 

• In terms of temperatures, I observed that the Core i9-12900KS averaged 65.1°C across my six tests. In comparison, the Core i7-13700K ran slightly cooler, at 64.5°C.
• Therefore, the Core i7-13700K is not even 1% better than the Core i9-12900KS in terms of thermal performance when it comes to 1080P gaming.

CPU Cost And Electricity Prices

Since the Core i9-12900KS costs almost half of its launch MSRP now (around $419), it’s evenly matched with the Core i7-13700K (~$417) in terms of CPU prices. Furthermore, both CPUs support the same chipsets, so the question of platform costs does not come into consideration. 

The two CPUs also share very similar power draw ratings. However, the Core i7-13700K is the more efficient CPU at a base frequency and could be slightly more economical if you’re running your CPU at stock settings.

In my 1080P gaming performance analysis, I found that the Core i7-13700K was 7.1% more power-efficient than the Core i9-12900KS. But, since the Core i7-13700K has a slightly higher boost TDP rating, it could cost more if your focus is on 4K gaming or productivity tasks.
