Notes
Covered by the "Xeon Scalable Processors" (1st Generation) entry on Microsoft's Windows 11 supported Intel processor lists; Windows 11 26H2 shares the 25H2 hardware requirements. TPM 2.0 must be provided by the platform. Mainline Linux supports Skylake-SP, and most systems run Windows Server or an enterprise Linux distribution.
