Intel launched several patches for the Linux series of operating systems to aid in increasing Alder Lake's performance through the P and E cores, or Performance and Efficiency cores.

With the release of Intel's 12th Gen Core Alder Lake series of CPUs, it was discovered that performance for the new CPUs was more efficient in Microsoft Windows 11 than in the Linux operating system. This is due to Linux not having adequate support for Intel's Thread Director technology that allows for the operating system to access high-performing Golden Cove cores and the energy-efficient Gracemont cores properly. Intel's Thread Director is created from the Enhanced Hardware Feedback Interface or HFI.
