In lieu of Optane persistent memory, Intel’s official strategy is to pivot towards CXL memory technology (CXL.mem), which allows attaching volatile and non-volatile memory to a CPU over a CXL-capable PCIe bus. This would accomplish many of the same goals as Optane (non-volatile memory, large capacities) without the costs of developing an entirely separate memory technology. Sapphire Rapids, in turn will be Intel’s first CPU to support CXL, and the overall technology has a much broader industry backing.
