Intel Demos 3D XPoint at IDF Shenzhen

Intel 8 3D Xpoint

First unveiled mid last year, 3D XPoint has been hailed as the next step for memory. Created in cooperation between Intel and Micron, the new memory technology is expected to serve as both a DRAM and NAND replacement in the future. While we all knew it would be crazy fast compared to NAND, we got the first glimpse of its true speed this week during Intel’s demo at IDF Shenzhen.

Unlike NAND flash which has to be written in pages and erases in blocks, 3D XPoint is addressable on the byte level. This gives much lower overhead and allows for higher speeds, especially in random performance. During the demo, the Optane device was able to reach 1.9GB/s in sequential performance. Furthermore, even when conducting random operations, the drive was able to hit 464,300 4K random IOPS. That’s about 1.9 GB/s as well, something current NAND-based SSDs, even NVMe ones, can’t reach. 3D XPoint seems almost symmetrical when it comes to read/writes and sequential/random performance.

Even with all the demos out, both Intel and Micron have been mum about a specific timeline for 3D XPoint to finally reach market. So far, all we know is that there will be 3D XPoint based SSDs set to arrive sometime this year. Hopefully, that will be sooner rather than later.
