grep -E "family|model|stepping" /proc/cpuinfo | uniq If you see model : 142 , congratulations, you are on Alder Lake.
If you see this CPUID, ensure you are running kernel 5.18 or later for optimal Alder Lake performance. For Windows, stick to Windows 11. How to verify this yourself? On Linux:
If you are running an old OS (like Windows 10 pre-21H2 or an ancient Linux kernel) on this chip, you might experience thread scheduling weirdness. The OS might try to put a background task on a fast P-core (wasting energy) or a game thread on a slow E-core (killing frame rates).
So next time you see that string in a log file, don't ignore it. Recognize it as the mark of —a processor that is trying to be both a race car and a scooter at the same time.
