Intel's 'Razor Lake' CPUs Edge Closer, Bringing New Security and AI Instructions

Intel has updated its official programming guide, confirming new model IDs for upcoming 'Razor Lake' desktop and laptop processors and 'Coral Rapids' server chips. The documentation reveals these CPUs belong to the same architectural family as the next-gen 'Nova Lake' chips, sharing key instruction sets. The technical update includes new security and virtualization features. Razor Lake gains more granular control over speculative memory behavior, while both families add APIC-Timer Virtualization for better virtual machine performance. Coral Rapids receives a dedicated instruction (VPMLDSABFLYDQ) to accelerate quantum-resistant digital signatures, a move aligning with future cryptographic standards. For engineers, this means software can be prepped for more efficient, secure workloads, marking another incremental step in Intel's multi-generational CPU roadmap.
