Intel Core i9-12900K: The most powerful gaming processor today

After testing the cheaper Core i7-12700K, we will take a look at Intel’s flagship today. Of course, the Core i9-12900K has higher performance. Is it worth paying six thousand extra for it? Do you really get that much extra power? This will show our test, including an interesting undervolt.

At the moment, you know the performance of the Core i9-12900K from hundreds of foreign reviews, we first released the Core i7-12700K test because this cheaper model will probably be more attractive in our country and will not appear so often in the initial reviews. In the end, there were really only a few of them worldwide. They all tested primarily the highest model supplied by Intel in the test suite.

The Core i7-12700K showed great performance, quite solid consumption outside the application with full load of all cores, the potential for further overclocking and nice gaming performance. We also said everything important about the Intel Z690 platform in the previous article. We looked at DDR5, PCIe 5.0 and tested the impact of Windows on performance.

As it turned out, and many foreign sites have confirmed, the difference in performance between Windows 10 and 11 is very small and differs significantly in only a few applications. So no matter what system you use, Alder Lake will work similarly in both versions of Windows.

Although I did not test the difference between DDR4 and DDR5, it turned out that the difference is also small. If you don’t have DDR5 with a speed of at least 5200 MHz and higher, it’s better to stick to DDR4 with nice timing and frequency. However, I support the DDR5 recommendation at the end of the previous review. They won’t bring you a big performance boost, but if I buy Alder Lake now, I’ll take the DDR5 board and modules. You can buy much faster memory over time and upgrade will be easier. Necessary condition for Alder Lake but DDR5 are not.

What we will try in the test

In addition to the obligatory benchmarks for comparison with previously measured processors, I would like to focus a little in depth on several aspects of Alder Lake. The classic performance comparison will not bring anything new, you have already seen it in about a million reviews that have been published so far.

I’ll take a closer look at consumption, measure real power consumption in a dozen different applications and games. I will also compare IPC Golden Cove architectures and older architectures. I will also pay more attention to the game performance. I’ll check more games than usual in CPU tests. In addition to overclocking, I will also try undervolt, so we will try to reduce the consumption of the Core i9-12900K to the level of Ryzens 5000 and compare their performance. This could be interesting in today’s rising electricity prices.

Alder Lake models

Let’s review the new generation of Core processor models in this chapter. As Intel is accustomed to, of course, the various CPU models of this architecture are distinguished by the number of cores, both P-Cores and E-Cores. The full configuration is intended only for the highest Core i9-12900K model and variants derived from it. We have 8 active P-Cores and 8 E-Cores here. Due to different architectures, both types of cores also operate at different frequencies. You see them in the table.

The table shows the first wave of chips that hit the market on November 4. More models are not expected until January 2022. For players, the Core i5-12600K model seems to be the most advantageous, and it will be affordable. At the moment, the state Core i9-12900K is about 19,000 CZK, Core i7-12700K around 13,000 CZK and Core i5-12600K is about 8,000 CZK. Personally, I expect prices to rise due to interest in chips, as they are unobtainable the day after the reviews in most stores.
