Alder Lake is still not fully supported by Linux (improvements are coming with v5.18¹, which is not stable yet, and it will take a while to be released into several linux distros (at least the Ubuntu based)).
It's a shame, because it would have been a great moment to offer an AMD alternative.

- howinteresting 4y agoThink most distros have backported the Alder Lake patches to their kernels.
- smoldesu 4y agoAlder Lake works just fine on Linux, it's only Thread Director which is missing. Not that these machines would really even need it, the current CPU prioritization code seems to work surprisingly well.
- ripley12 4y agoThings are fine on Linux even without Thread Director support. I've been running Fedora 36 (kernel v5.17) on a 12900K for a few months now without any noticeable issues.
- pizza234 4y agoAccording to the article above, Linux pre-5.18 will mostly choose P(erformance) cores. On a desktop context, this may go unnoticed (so, in your cases like yours, it's not a problem at all), however, in a laptop, it will make the CPU inefficient, defeating the point of the Alder Lake design.
