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

Famous hardware leaker HXL Published what is purported to be Intel’s Optane Persistent Memory roadmap. This 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 use a DDR-T2 interface featuring data transfer rates from 4000 MT/s to 4400 MT/s, resulting in a significant performance boost over their predecessors. This gives 2R1W random bandwidth up to 3 GB/s and 2R1W sequential bandwidth up to 6 GB/s per module.

Additionally, Intel promises opportunistic bandwidth increases of up to 25% per CPS. The new module is significantly faster than the previous module, but still consumes about 15W.
