> More troubling is endurance, probably the main selling point of this technology over NAND. Again the claim was a 1000x improvement, Intel delivered 1/333rd of that with 3x the endurance.
From this seminar few months back - https://www.youtube.com/watch?v=hXurTRtmfWc ,
I think density can be increased, this is only the initial product,
and latency is contributed more by PCIe/OS/application rather than the underlying 3d-xpoint material. The slides from the article are for the PCIe SSDs, I wonder whether the earlier claimed latency, still holds well with NVRAM.
I wonder why the endurance is so lower than the earlier claims.

#3So disappointing... I'm wondering if they did it intentionally to make room for an upgrade(i.e like the TV industry did with 8K)
Re: Intel’s Xpoint is broken
#4The new numbers Intel is claiming, can be met by floating gate transistors that are randomly accessible (versus those arranged in bit lines and word lines like in NAND). Especially for a single level cell. No need for another materials science/physics like "x point", unless"x point" actually is just a PR spin without any new physics.

It seems to be a case of transitioning marketing claims from those about the potential of the core underlying technology to more real world scenario benefits. Some of the numbers included latency in the kernel/driver, so they are more focused on actual applications.
It is a bit different to say initial product shipped vs tech potential.. We've been waiting on zen err bulldozer/excavator/piledriver/steamroller for years now, and while mobile and Apus shipped, it has been a fluke in server and desktop markets.

#6One should not confuse 3D XPoint that is a sort a memory and Optane that is a product, a SDD. Octane uses all the traditional protocols to work like other devices in a computer and that slow down the operations a lot. We saw the same drawbacks with SDD when they used the SATA interface and the protocols of hard drives, before special drivers improved their speed.

#7How is it "broken"? I thought they meant that there's a fundamental flaw with the tech, but instead it seems he just means that they didn't meet their original goals of the tech with their first actual product.

Can you please explain this in layman's terms?

SemiAccurate - the website this article is posted on - is a bit like the Daily Mail of technology. It probably had clickbait titles before the word was coined.

perfectly named though—truth in advertising FTW!
