Intel and Micron jointly launched XPoint technology over a year ago, and we've been waiting to see any additional info ever since. We saw Micron demo a prototype at FMS 2016, and we also saw the actual prototype. Intel's last demo was not so great, later demos were better), and we saw a roadmap leaked a few months ago. Thanks to another leak, we now have specs for one of Intel's first Optane products:
Now I know there is a bunch of rambling around the net already. "Why so small?!?!". What I think we are looking at is Stony Beach - Intel's 'Application Accelerator" seen here:
What further backs this theory is that you'll note the PCIe 3.0 x2 link of that product in the above roadmap, which couples nicely with the upper end limits seen in the 32GB product, which is clearly hitting a bandwidth limit at 1.6 GB/s, which is the typical max seen on a x2 PCIe 3.0 link.
Now with the capacity thing aside, there is another important thing to bring up. First gen XPoint dies are 128 Gbit, which works out to 16 GB. That means the product specs for the 16GB part are turning in those specs *WITH ONE DIE*. NAND based SSDs can only reach these sorts of figures by spreading the IO's across four, eight, or more dies operating in parallel. This is just one die, and it is nearly saturating two lanes of PCIe 3.0!
Another cool thing to note is that we don't typically get to know how well a single die of anything will perform. We always have to extrapolate backwards from the smaller capacities of SSDs, where the dies are the bottleneck instead of the interface to the host. Here we have the specs of one die of a product. Imagine what could be done with even wider interfaces and more dies!
XPoint fills the still relatively large performance gap between RAM and NAND, and does so while being non-volatile. There are good things on the horizon to be enabled by this technology, even if we first see it in smaller capacity products.
