    we knew intel couldnt make sillicon but looks like they cant even make slides anymore LUL

    These are phenomenal for databases, since databases are random access lookups. I'd like to see Optane DCPMM benchmarks with Postgres.

    At the current price levels the only use case for Optane DIMMs is restarting the database system or the whole server system regularly. In all other cases a couple of NVMe SSDs and more RAM are much cheaper. This has been true since Optane DIMMs came to market.

    That's a use case for small-scale workstations. For price-doesn't-matter servers, Optane Memory means data sets stored in much bigger main memory.

    And eventually the prices will go down as well.

    It wont matter if the storage across the network. It would only be faster if its instance storage and you are commiting to a single node. the moment you wanna commit to 2 or more nodes (mongodb replicasets for example) or storage is across the network (AWS RDS) it wont matter.

    Faster transaction processing is purely theoretical and completely meaningless in practice. Optane's only advantage is 2x better density for a 3x worse latency. and with dram prices where they are its not enough to make ppl rewrite software.

    correction:

    +2x better density
    -3x worse latency
    -10x worse random bandwidth
    - who knows about wear and tear (much worse than DRAM)

    why no edit feature?

    Am I reading this correctly? They're just re-iterating the benefits of Gen 1 3D XPoint?

    Good grief, everything at Intel's delayed, not just stuff relying on 10nm.

    its actually an order magnitude downgrade on what they were saying in 2015/16
  • extide - Monday, August 19, 2019 - link

    Note really -- they said 1000x earlier, and they are showing 500x here:

    "100 microseconds for normal SSD vs Optane SSD (10 microseconds) vs Optane DCPMM (0.2 microseconds)"
  • azfacea - Monday, August 19, 2019 - link

    z-ssd is not any where close to 100 microsecond. they've also revised down density and wear and tear claims big time.

    even then walking it back 2x after 4 years is hardly impressive

    You write a lot, yet provide no supporting evidence.
  • azfacea - Monday, August 19, 2019 - link

    "You write a lot" yea if you don't like that fuck off. you are in the wrong place not me.

    might be too hard to comprehend for you but its called online comments where ppl "commnet".
  • Korguz - Monday, August 19, 2019 - link

    azfacea, just ignore Phynaz, he doesn't provide proof of anything he says HIMSELF, and then just insult and call people names, when he gets call out on it, or gets asked for proof

    Samsung says Z-SSD is 20usec, and no-one has disagreed with that:

    I must have sat through about ten Intel NDA briefings in the last four years and 3D Xpoint/Optane was always the most boring topic. A solution in search for the right problem. By now I just tune out when it comes up. And I also don't know anybody else who would care.
  • remosito - Wednesday, August 21, 2019 - link

    DB Server guy here. Care a lot.
  • name99 - Wednesday, August 21, 2019 - link

    For what purpose?
    Larger transient address space (so basically like a very fast VM)?
    Or persistence? And if persistence, to bypass file abstraction latency? Or something else? Ie what’s the win over Optane nvme?
  • name99 - Wednesday, August 21, 2019 - link

    Intel thinks Optane SSD is slower than flash? (2nd slide)
    WTF? The marketing machine really is off the rails now...
  • name99 - Wednesday, August 21, 2019 - link

    Oops, my bad
    It’s not Optane that’s worse than generic SSD, it’s just Intel 3D NAND.
    OK, then...
