Intel’s Optane Persistent Memory Roadmap Surfaces Online, Focused on Xeon Lineup

A purported roadmap for Intel’s Optane persistent memory was provided by renowned hardware leaker HXL. The slide describes the forthcoming Crow Pass Persistent Memory 300-series modules for Intel’s Sapphire Rapids and Emerald Rapids processors.

The Optane PMem 300-series Crow Pass modules from Intel will perform far better than their forerunners thanks to their use of a DDR-T2 interface with a 4000 MT/s to 4400 MT/s data transfer rate. As a result, each module will have a maximum 2R1W sequential bandwidth of 6GB/s and a maximum 2R1W random bandwidth of 3 GB/s. Additionally, Intel guarantees an opportunistic bandwidth boost of up to 25% per CPS. The new modules will still use roughly 15W even though they will be far faster than their forerunners.

Optane Persistent Memory modules from Intel will still be available in 128GB, 256GB, and 512GB sizes. Up to 4TB of 3DXPoint memory will be supported by Intel’s forthcoming Eagle Stream platform, which has an eight-channel memory subsystem. The Crow Pass modules from Intel comply with FIPS140-3 level 2 criteria, which is another advancement. The modules will continue to utilize AES-256 encryption on the hardware side, much like earlier models. 

While Intel has formally given up on Optane memory and there won’t be any more SSDs using 3DXPoint memory, the company is still on track to release another family of Optane Persistent Memory 300-series modules for its Eagle Stream platform, based on its 4th and 5th Generation Xeon Scalable processors, codenamed Sapphire Rapids and Emerald Rapids.

In the next years, when there will be a need for a lot of relatively inexpensive memory close to the CPU, these Optane PMem modules will support Intel’s Xeon Scalable platforms.
