EXPLAINED: Intel drops optane persistent memory support from emerald rapids | Vintage Vibes

Intel Corporation Memory Xeon

Intel

Intel's next-generation Xeon Scalable processors (codenamed: Emerald Rapids) and their successors will cease support of the company's Optane Persistent Memory (PMem) modules, according to the company's own PerfMon tool, as discovered by InstLatX64. Apparently, Intel is now betting on CXL 2.0 memory expansion modules.

Intel's Emerald Rapids heavily relies on technologies developed for Sapphire Rapids, as it uses the same high-performance microarchitecture and shares the platform. That said, removing Optane Persistent Memory support looks to be a business, rather than a technological, decision. Keeping in mind that Intel will stop officially supplying Optane Persistent Memory modules on Dec. 29, 2023, it is logical not to support it on products that ramp in 2024.
