The world has been eagerly awaiting the debut of 3D Xpoint memory technology since we first learned about it back in 2015. And it is finally here – sort of.

Intel just announced their newest family of products, dubbed Intel Optane Memory. More than a simple upgrade, it provides an entirely new form of memory for your computer. Based on the 3D Xpoint architecture we’ve been waiting for, it is said to be as fast as the DRAM memory found in modern-day PCs while still maintaining the stability of the NAND memory used in the solid state drives of our smaller devices. And what’s even better, it can be easily added to your PC via the M.2 slot on your motherboard.

Intel’s Senior Vice President Navin Shenoy says Optane is “the biggest advance in memory in decades.” While this may be a bit of an overgbrag, considering how huge the introduction of NAND memory was a few years back, its promises are nonetheless impressive. The desire for a non-volatile version of DRAM has been a goal almost since the day it was invented, and Optane is a step in that direction. It works in conjunction with DRAM to provide the sort of benefits that most of us attribute to SSDs (Solid State Drives) – think faster launch, save, and load times for the applications and files you use frequently. Plus since it’s non-volatile, the Optane won’t reset when you turn off your computer the way RAM does. In lament’s terms, things will still run faster each time you launch an app (after the first time, of course), even if you reboot your computer between uses. And since it’s adaptable, accompanying drivers and software will learn what you use most frequently and subsequently add those things to the same up-front cache. It achieves this by caching your most frequently accessed bits of data on a system and then storing them on the Optane Memory module for quicker access.

According to IDC data cited by Intel, roughly 80 percent of desktop PCs in the world still use hard drives. Average stats for PC users indicate that they open between 11 and 14 unique applications a day, launching each between seven and eight times in a given day. By that math, users should see an overall boost to performance roughly 75 times each day of use – not too shabby. There are a few caveats, though. As it stands, Optane memory will only be available for desktop computers with Kaby Lake processors and “Optane memory ready” motherboards. But according to Intel, nearly every new motherboard built for the Kaby Lake infrastructure and above will include a slot for Optane memory. They even plan to start featuring the new memory tech in laptops as soon as this year, and insist that it will work with any internal storage

The Optane memory will come in two different sizes when it goes on sale on April 24. The 16GB version will set you back a meager $44, while the 32GB version will retail for $77.
