Abstract:
The 063rd version of the architecture instruction set extended programming reference document has been exposed, solidifying Intel’s iterative route for next-generation processors. The document details the CPUID identification codes of consumer processors code-named Razor Lake and Coral Rapids server processors, indicating that these two architectures have entered a substantial development stage.
According to Intel's current roadmap, Razor Lake will serve as the successor to Nova Lake and become the main architecture in the desktop and notebook markets around 2028. Coral Rapids is positioned as the next-generation Xeon server platform after Diamond Rapids.
To put it simply, the CPUID identification code is the key basis for software to identify the processor's identity and supported features. This disclosure means that the underlying software ecosystem has begun to make early adaptations for these "future-warming" hardware.
In terms of platform segmentation, the CPUID identification code patterns of the Razor Lake desktop version are 300F6x and 300FAx, and the notebook version is 300F7x and 300F9x.
It is worth noting that according to previous reports, the Razor Lake-S desktop series will continue to use the LGA 1954 interface, which is undoubtedly good news for hardware enthusiasts who want the platform to last longer.
Coral Rapids on the server side has an independent identification code of 400F8x, showing a clear distinction between its architectural design and consumer-grade products.
In terms of technical features, Razor Lake introduces a security feature called SSBD_PSFD_U_S, which can provide more detailed user-mode and kernel-mode control for specific predictive execution memory operations.
And the new architecture also supports APIC-Timer virtualization technology, which is a hardware solution that optimizes the efficiency of timer event processing in a virtual machine environment.
At present, this document mainly serves software developers and does not contain specific frequency, core number or actual performance test data.
Since the expected launch time of 2028 is still early, there are still many variables in Razor Lake’s final retail name, manufacturing process and specific graphics card matching plan.
