Presenting at the UBS Worldwide Technological innovation Conference these days, Navin Shenoy, Intel Govt Vice President and Basic Supervisor of their Info Center Team, shared an update on Intel’s roadmap for 3D XPoint DIMMs. Intel claims that they are on monitor to start 3D XPoint memory modules in the next half of 2018. They are projecting that 3D XPoint DIMMs will be an $8B market by 2021.
Just after launching quite a few Optane SSD merchandise this year based on 3D XPoint memory, Intel experienced mentioned virtually almost nothing about their development toward 3D XPoint DIMM memory modules. Intel to start with publicly confirmed a prototype 3D XPoint NVDIMM in January 2016, only a couple months after unveiling 3D XPoint memory alone. When the to start with Optane merchandise launched earlier this year, we were advised Intel would have additional to say on the subject matter of 3D XPoint DIMMs in 2018, but modern announcement makes it obvious they will be advertising the actual components within just about a year.
The start of 3D XPoint DIMMs will depend on quite a few parts coming collectively. Very first, Intel’s 3D XPoint memory have to be sufficiently experienced to meet up with the general performance and stamina demands of DIMM-based usage. Their Optane SSDs have all applied a PCIe and NVMe interface that adds substantial latency overhead and makes it difficult to evaluate how close the fundamental 3D XPoint memory can appear to DRAM general performance ranges. The Optane SSDs are also delivery with relatively conservative generate stamina ratings relative to the eventual expectations for 3D XPoint merchandise: The Optane SSD DC P4800X’s 30 travel writes for every working day for 5 many years is not considerably higher than higher-stamina flash-based enterprise SSDs can deliver.
2nd, Intel will require to continue raising creation of 3D XPoint memory as their spouse and children of Optane SSDs expands and is joined by 3D XPoint DIMMs. Yesterday, Intel and Micron celebrated the completion of an enlargement to developing sixty of their IM Flash creation services in Lehi, Utah. This will considerably increase their creation ability of 3D XPoint memory. So far, Intel would seem to have been applying virtually all of the creation of 3D XPoint memory for their Optane merchandise when Micron has yet to publicly introduce any mass-produced 3D XPoint-based merchandise. Micron will most most likely get started asserting and delivery 3D XPoint merchandise under their QuantX model within just the future year, so Intel will never be finding the total reward of this ability strengthen.
3rd, 3D XPoint DIMMs will involve server platform assistance because they are unlikely to operate as normal DDR4 DIMMs. The JEDEC NVDIMM-P normal for persistent memory DIMMs has not been finalized and is envisioned future year. It’s not particular no matter if the 3D XPoint DIMMs will adhere to the NVDIMM-P normal or if they will use a proprietary interface, but either way they are most likely to involve current CPU and motherboard assistance. Intel’s not too long ago-launched Xeon Scalable platform can assistance DRAM+flash NVDIMM-N modules. The start future year of 3D XPoint DIMMs could foretell a simultaneous refresh of the Xeon Scalable platform.
