Intel Confirms HBM is Supported on Sapphire Rapids Xeons

Intel has simply launched its “Architecture Instruction Set Extensions and Future Features Programming Reference” handbook, which serves the aim of offering the builders’ details about Intel’s upcoming {hardware} additions which builders can make the most of afterward. Today, because of the @InstLatX64 on Twitter we have now info that Intel is bringing on-package High Bandwidth Memory (HBM) answer to its next-generation Sapphire Rapids Xeon processors. Specifically, there are two directions talked about: 0220H – HBM command/tackle parity error and 0221H – HBM information parity error. Both directions are there to deal with information errors in HBM so the CPU operates with appropriate information.

The addition of HBM is simply one of many many new applied sciences Sapphire Rapids brings. The platform is supposedly going to convey many new applied sciences like an eight-channel DDR5 reminiscence controller enriched with Intel’s Data Streaming Accelerator (DSA). To hook up with the entire exterior accelerators, the platform makes use of PCIe 5.zero protocol paired with CXL 1.1 customary to allow cache coherency within the system. And as a reminder, this could not be the primary time we see a server CPU use HBM. Fujitsu has developed an A64FX processor with 48 cores and HBM reminiscence, and it’s powering as we speak’s strongest supercomputer – Fugaku. That is displaying how a lot can a processor get improved by including a quicker reminiscence on-board. We are ready to see how Intel manages to play it out and what we find yourself seeing in the marketplace when Sapphire Rapids is delivered.
