Test: Disabling small (E) and big (P) cores of the Core i9-12900K

Performance tests

The big.LITTLE concept in Intel Alder Lake processors encourages various “re-configurations” of the cores. Especially in the context of inferior scaling or priority settings that are not good for some applications. However, user interventions in this direction will more often lead to a disservice than to a benefit. Does it make sense to bypass E cores in games? It doesn’t. Such intervention drives processors into severe inefficiency.

Performance tests

We didn’t get to test everything in turn according to the standard methodology for processor tests, but we got the key stuff. We’ve gone through all the tests, alongside which we also monitor and chart power consumption, heating or core frequencies. So three computational tests, the same number of gaming tests, but also measurements off-load.

In this chapter and in the following chapters, we leave the results without comment. Read through them, make your own picture, and finally, you can stop in the final chapter, where we will comment on the measured results.
