3D XPoint Storage On The Way
#1
http://techreport.com/news/28712/intel-m...int-memory
Whistles.
Quote:3D XPoint (pronounced "3D cross-point") is described as a high-performance, very dense, non-volatile memory, and it's meant to help computers get more data closer to the processor. Crooke says it's a thousand times faster than today's flash memory and a thousand times more durable. Compared to DRAM, 3D XPoint is ten times as dense, and it's non-volatile. The initial 3D XPoint memory chips pack 128Gb on each chip, and that number is expected to increase as more layers are stacked on each chip.
...
Both firms are developing products based on 3D XPoint, and the memory will begin sampling "with select customers" later this year.

That is, 16GB per chip.  Phenomenal.

So next year would be when we'd be seeing retail samples?  

This is too much of a revolution.  

Makes Skylake feel like a waste of an upgrade when this tech is right around the corner..   Cannonlake should feature this if Intel is "developing products based on 3D XPoint".  



Let me see if I can get the next couple years right (if my crystal ball is any good):

I5-variants of desktop Cannonlake with a bit of edram L4 cache, 8GB HBM2 memory, 128GB 3D XPoint memory for storage and instant loading of Windows 10 SP1 and main apps, and 4TB HDD that drops to around $100.  
Customer i7-variants with 16GB HBM2 memory.  256GB 3D XPoint afforable by these customers as well, so still no great need for an SSD when a 4-6GB 7200rpm HDD serves the rest of storage needs.
Enthusiast i7-variants with 32GB HBM2, perhaps 512GB 3DX XPoint as the top line, 2TB M3 SSD's, and also 8TB HDD's for archiving.

This is a massive revolution.  Windows 10 would be just like the Win XP era.  PC's that first ran WinXP compared to the PC's that ran WinXP during the end of the XP era were like night and day, with these early 1GHz single-threaded PC's completely obsolete by then.  Then PC's that first ran Vista (core2quad, still as fast as most of AMD's offerings today) are still considered decent and fine for running most things nowadays, on Windows 8.1..

There are many new technologies that never take off. The drawbacks, pros vs cons, and even politics can have a major influence in the direction we go.

Quote:Meanwhile unlike many next generation memory technologies out there at the moment, 3D XPoint is the furthest along and doesn't only exist on paper or in a lab. Intel and Micron are currently sampling the first generation die that is being produced at the companies' jointly owned fab in Lehi, Utah. The die is 128Gbit (16GB) in capacity, whereas the products that startup memory companies have in production are in the order of dozens of megabytes. The die is built on a 20nm node and consists of two layers, and in the future scaling will happen through both lithography shrinks and by increasing the number of layers.

The Utah fab has been producing 20nm NAND for now since Intel didn't invest on the 16nm shrink and all initial 3D NAND production will take place in Micron's Singapore fab, but it's unclear whether the full fab with its 20,000 wafers per month capacity will be dedicated to 3D XPoint from now on. My guess would be that 3D XPoint will gradually take over the full wafer capacity in Utah depending on how the market reacts to the new technology and how high demand Intel and Micron are seeing. 3D XPoint does require some new equipment for manufacturing since 3D XPoint deals with a whole new set of materials, but Intel and Micron said that the transition is quite similar to a new NAND node and allows some of the existing equipment to be used.

The companies aren't quoting any price per gigabyte yet, but since the whole function of 3D XPoint is to fill the gap between DRAM and NAND, it will also be priced accordingly. A quick look at NewEgg puts DRAM pricing at approximately $5-6 per gigabyte, whereas the high-end enterprise SSDs are in the range of $2-3. While client SSDs can be had for as low as $0.35, they aren't really a fair comparison because at least initially 3D XPoint will be aimed for enterprise applications. My educated guess is that the first 3D XPoint based products will be priced at about $4 per gigabyte, possibly even slightly lower depending on how DRAM and NAND pricess fall within a year.

Wow, this is utterly exciting. Most exciting thing since SSD's, but I'm actually more excited about this that I ever was about SSD's.

Quote:
  • The Optane SSD was able to achieve 7.2x times more IOPS at low queue depth and upto 5.21 times the IOPs of conventional SSDs at high queue depths.
  • An Optane Technology based SSD has 10x times the density of conventional SSD drives.
  • The marketing material also claims it is 1000x faster than the competition available on the market but it isn’t clear to what exactly they are referring to – a good guess would be latency, as opposed to bandwidth.
  • Optane SSDs will have 1000x the endurance – which, if true, should mean the device has virtually unlimited life span for practical purposes.

Also, regarding the DIMMs:

And the really exciting part:

Quote:While one would guess a insanely high price for these new products, Intel has promised a suggested pricing comparable to current flash and DRAM products which will mean that Optane branded products will become economically viable to gain a larger user base when its launched due to high competitive pricing.

With 10x the density of conventional SSDs (and 1000x the reliability), perhaps this spells the true death for mechanical HDD's.

Quote:What was great about the whole announcement was that Intel’s new technology wasn’t just some proof-of-concept pipe-dream, but was instead in full production with a wide release scheduled for this year. Unfortunately, it looks like Intel has run into trouble and has silently and significantly postponed the launch of 3D XPoint tech.

Spotted by Motley Fool, Intel’s plans seem to have shifted, given that the upcoming server Skylake EP processors will not support 3D XPoint. Instead, it looks like the first server systems to support the new memory tech will be coming out as late as 2019.

This is very disappointing, given that earlier this year Intel was rumored to be working with partners on developing 3D XPoint SSDs and that its tech has been in testing for so long. Still, server-side support is one thing, consumer electronics is another. Here’s hoping we’ll still see this tech show up on the market so we can all ditch our slow, puny M.2 SSDs.

Quote:The first big announcement is that Lenovo is launching Intel Optane caching drives on select ThinkPad models. We’ve followed the development of this new non-volatile storage solution for some time, and please check out the full write-up on this announcement of shipping 3D XPoint here. Due to the small storage capacity, these initial Optane M.2 drives will be used for HDD caching on several ThinkPad models, including the ThinkPad T470p, L470, L570, T470, and T570.
