The next-gen Intel Xeon Scalable processors, codenamed Emerald Rapids, will apparently no longer support Optane Persistent Memory modules. The discovery was made through the company’s PerfMon tool, and while the decision may be a business one, it’s still a bit of a bummer for enthusiasts hoping to see Optane PMem support on upcoming products.

Intel’s Xeon platform is a big one, and Emerald Rapids will be the company’s first 14nm processors to support the new generation 16nm process node. Simply put, that means better performance and efficiency, which is what everyone wants from their servers and desktops.

Emerald Rapids shares the same microarchitecture as Sapphire Rapids, so removing Optane support from next-gen Xeon parts makes sense, especially since the company will be supporting CXL 2.0 memory expansion modules.

In fact, Intel will stop supplying Optane PMem modules on December 29, 2023, so not supporting it on 2024 products is a logical business move. The company will still support Optane SSDs, but it’s uncertain how many vendors will validate their work with newer platforms.
