Micron's XPoint/QuantX memory is set to come in at 4-5x the price of NAND, with 10x lower latency and performance and over 10x the IOPS at low queue depths. 

These performance numbers are when compared to an Intel P3700 NVMe SSD, which in itself offers some of the best NAND performance that can be seen today. In the picture below (courtesy of PCPER)  we can see that MIcron's XPoint, now called QuantX, memory offers some huge performance gains when used at low queue depths, a typical performance weak spot on today's NAND based SSDs. 

Micron also showcased greatly decreased latency with their new QuantX memory, offering average read/write latencies which are 10 times lower on average, making this new memory type much quicker to respond than NAND.

In the graph above we can see that all of the QuantX powered devices seen here can easily saturate an 8x PCIe connection with ease at low queue depths, making a mockery of the 1600GB NAND based SSD that Micron tested. 

On a cell-by-cell level Micron's QuantX memory will offer around 1000x the performance of NAND flash, though in reality at larger queue depths and more typical workloads this performance gains is actually around a 10x performance improvements.  This improvement is still nothing short of astronomical, pretty much saturating the PCIe 3.0 bandwidth that is used to communicate with your system.

Micron now states that 3D QuantX/XPoint memory will come in at around 4-5 times the price of NAND flash, meaning that it will be a long time before affordable QuantX powered SSDs make it to consumers. 

It is expected that Micron will receive their first revenues from QuantX memory in the second half of 2017, with the new memory type playing a bigger role in their 2018 and future earnings.
