Intel has updated its Architecture Instruction Set Extensions Programming Reference, adding details on the upcoming Razor Lake and Coral Rapids architectures. The document, revised to version 063, provides model identifiers for developers preparing software for these future chips.
Razor Lake is categorized under family 18 (12H), sharing this designation with Nova Lake. The reference specifies four model values: 12_06H and 12_0AH for desktop processors, and 12_07H and 12_09H for laptop variants. These chips are expected to support AVX10.2 and APX, similar to Nova Lake.
The Coral Rapids Xeon family is assigned model 13_08H, following the Diamond Rapids architecture at 13_01H. This line will support AVX10.2 and introduces the VPMLDSABFLYDQ instruction, which is designed for the ML-DSA quantum-resistant digital signature standard.
Both architectures include new features such as APIC-Timer Virtualization for virtual machines. Additionally, Razor Lake incorporates SSBD_PSFD_U_S, a feature that provides separate user-mode and supervisor-mode control over specific speculative memory behaviors.
