3D XPoint will dominate market beginning in the 2H ’18 Introduction of competing NVRAM products expected to begin ramp in 2H ’19 NVRAM replacing DRAM & NAND in mobile space in 2020 0015Socket7742018/02/17(土) 06:02:35.11ID:T19DZ95S Optane DIMMがDDR4並（非DDR）の速度の可能性も
Yet another kind of NVDIMM is scheduled to be introduced by Intel in late 2018. Intel’s “Optane DIMM” is based on the Intel-Micron 3D XPoint Memory, which is persistent and is said to perform at near-DRAM speeds. 0016Socket7742018/02/17(土) 06:03:21.31ID:T19DZ95Shttps://techreport.com/news/32841/intel-confirms-optane-dimms-for-late-2018
Chuckula and moose17145:
Optane DIMMs won't replace DRAM completely. DRAM is needed to act as a buffer for writes and for endurance.
I have one theory: Early leaks had 8 DIMM slots, which were strange because Purley only has 6 channels. I believe the 2 slots are for DRAM.
2x128GB DRAM + 6x 512GB Optane DIMM?
Technology always happens in steps, it NEVER comes all at once. This when it happens is a ground-breaking step to a much different computing future. 0017Socket7742018/02/17(土) 06:04:17.03ID:T19DZ95S DDR4等のメモリーは高騰しているので、Optane DIMMに期待したいところ 0018Socket7742018/02/17(土) 06:18:29.66ID:T19DZ95S IntelとMicron、2019年以降は3D NANDの共同開発体系を解消へ https://pc.watch.impress.co.jp/docs/news/1099981.html
Micron QuantXもあるが、「Intel-Micron Flash Technologies」(IMFT)のこともあるので、 3D XPointの連携は継続するという理解
Unfortunately, I do not have any numbers on how fast the Optane memory that will slot into the DDR4 slots will be, but seeing as two dies already max out the x2 PCI-E link they use in the M.2 Optane SSD, a dual sided memory module packed with rows of Optane dies on the significantly wider memory bus is very promising. It should lie somewhere closer to (but slower than) DDR4 but much faster than NAND flash while still being non volatile (it doesn't need constant power to retain the data). 0029Socket7742018/02/19(月) 12:43:58.31ID:eP13fZLd 2年前のニュースなので、optaneが発売される前となり今とは違うはずだが、6TBメモリー（NVDIMM）の実装例
The 3D XPoint NVDIMM utilizes the DDR4 interface to communicate directly with the CPU. Intel stated today that the current maximum capacity per 3D XPoint NVDIMM is 512 GB, and dual-socket servers can address up to 6 TB total with two CPUs. The largest DDR4 modules weigh in at a mere 128 GB apiece. To put the 6 TB per-server density server into perspective: Windows Server 2012 R2 supports only 4 TB of memory.
Microsoft also detailed its role for enabling NVDIMM functionality, and thus 3D XPoint, in a panel today. Microsoft has an in-house build of Server 2016 with a new file system designed specifically to address new ultra-low latency NVDIMM devices. NVDIMMs are a range of Storage Class Memory (SCM) products that utilize the memory bus and DRAM, NAND, and now 3D XPoint to provide ultra-fast storage performance.
