What happened

Intel has added Razor Lake and Coral Rapids to the November edition of its Architecture Instruction Set Extensions Programming Reference , the document developers use to prepare software for upcoming chips. Revision 063 gives Razor Lake four new model values under family 18 (12H), the same family as Nova Lake, with 12_06H and 12_0AH covering desktop parts and 12_07H and 12_09H covering laptops. Intel is a semiconductor and electrical company based in Santa Clara.

The Coral Rapids Xeon family gets 13_08H, following Diamond Rapids at 13_01H. InstLatX64 spotted the update and shared it on Bluesky.

The new feature entries are fairly small. Razor Lake picks up SSBD_PSFD_U_S, which seems to allow separate user-mode and supervisor-mode control over certain speculative memory behavior, while both families gain APIC-Timer Virtualization for virtual machines.
