For those who came in late, 3DXPoint is a next-generation non-volatile memory technology and is supposed to be faster than NAND flash memory while much cheaper than DRAM.
Intel had previously said that these 3DXPoint memory modules would be supported on a "future Intel Xeon processor". It was thought that Intel was referring to the Skylake-EP and this is expected in the first half of 2017.
However, on Intel's most recent earnings call, CEO Brian Krzanich indicated that this wouldn't be the case.
According to this, the "future Xeon processor" that will support 3DXPoint memory modules will not be the upcoming Skylake-EP but instead its successor, known as Cannonlake-EP.
If Intel's upcoming 3DXPoint memory modules require Cannonlake-EP to work, then investors should realistically expect that Intel won't be selling those modules until either late 2018.
