Intel Launches Site Detailing Optane Requirements: Skylake Users Need Not Apply

Microprocessor giant Intel has launched a new page dedicated to its 3D XPoint-based Optane memory solution, a technology that it jointly developed with memory manufacturer Micron back in 2015, and was supposed to be on the market by 2016. The company missed that date; however, the technology is still interesting to enthusiasts and power users alike, due to its promises of both high speed and large capacity, a seemingly unattainable combo in today's markets.

Unfortunately, it seems that any system built around when Optane was announced will not be able to run Optane-based SSDs. In the system requirements section of its page, Intel has indicated that Optane will not run on anything earlier than a Kaby Lake based CPU. No exceptions. Yes, that includes Skylake, Broadwell, and pretty much everything else besides Kaby Lake. You will also need a 200-series chipset or newer.
Skylake is amongst the most surprising of these exclusions, because it is nearly identical architecture-wise to Kaby Lake and a Skylake based chip was once used in a Optane test demonstration.

This probably means that Intel's upcoming HEDT Skylake-X is also not supported? :rolleyes:

Not so surprising when you think of the obvious money grab by Intel to encourage people to use the latest CPU.

Can't wait for Ryzen to give Intel a kicking.

AntDeekCan someone please explain to me how this is different than me just popping in a PCI-E m.2 SSD on my board? Seems confusing honestly
Because of its feature, the 3D-Xpoint can be used as a hybrid application of SSD and DRAM. So the scenario can make data much closer to CPU than NAND. The change will enhance the data rate and give rise to a evolvement of x86 architecture. But the drawback is 3D-Xpoint will consume more power.

Wouldn't Micron be able to release their version of Optane that is compatible with everything out there that Intel isn't willing to support? Seems like it would come down to a controller chip on a drive or M.2 card to communicate whatever protocol is used on that interface, be it DDR4, PCI-E, SATA or USB.

They aren't rushing anything...

And, the difference in ipc between skylake and broadwell-e won't help with what AMD is going to put out... Unless they process it accordingly...which I doubt.

Recently, I find the Everspin released the MRAM SSD that has much better performance than 3D-Xpoint. It seems that DRAM can be replaced by it in system. So if it is true, the data can be moved to DIMM location same as DRAM. At that moment, the performance can be improved further.
