Test: Alder Lake Intel i9-12900K and i5-12600K



Can we talk about a sensitive topic ? Recently, we announced in the news, the possibility of using the PL2 mode (max power consumption 241W) instead of the PL1 mode (TDP 125W). This has of course a direct impact on performance and therefore on scores.

On our side, we did not change anything and we wanted to see how our configuration would behave out of the box. We basically installed our CPUs and loaded the XMP profile. Then we did our series of benchmarks and compiled our findings for you in this article.

We wanted to measure power consumption and we decided to use Cinebench R23 benchmark. So we will be testing power usage in multi-threading. The idea is to measure the average power consumption of our different CPUs.

Please be aware that we are talking about the overall power consumption of the build, and not the CPU alone. Currently, we are not yet able to measure independently and correctly the consumption of the CPU. But this is in progress.

As you can see, the average power consumption of our configuration is 321.1 watts. Compared to the previous generation i9-11900K, this is much better. Let’s not forget that we are dealing with an 8C + 8c processor. Against the Ryzen 9 5950X, our Alder Lake does not manage to match its level of power efficiency, even if the difference is not that big.

The i5-12600K, however, is a the great surprise, as its overall power consumption is only 214.2 watts. Thanks to our tests, it gets our approval and we had a lot of good things things to say about it.
