Optane’s Last Gasp: Intel’s Final Persistent Memory Roadmap Leaks

Posted on

Renowned hardware leaker HXL has published what is claimed to be Intel’s Optane Persistent Memory Roadmap. The slide details the company’s upcoming Persistent Memory 300-series modules, codenamed Crow Pass, for Intel’s next-generation Sapphire Rapids and Emerald Rapids processors. 

Intel’s Optane PMem 300-series Crow Pass modules will offer substantial performance improvements over predecessors, as they will use a DDR-T2 interface featuring a 4000 MT/s to 4400 MT/s data transfer rate. This will result in up to 3 GB/s 2R1W random bandwidth, as well as up to 6 GB/s 2R1W sequential bandwidth per module.

Furthermore, Intel promises an up to 25% opportunistic bandwidth increase per CPS. Although the new modules will be significantly faster than their predecessors, they will still consume about 15W.

Intel will continue to offer Optane Persistent Memory modules in 128GB, 256GB, and 512GB capacities. And since Intel’s upcoming Eagle Stream platform features an eight-channel memory subsystem, up to 4TB of 3DXPoint memory will be supported.
