Samsung juices its HBM2 to 2.4 GT/s and names it Aquabolt

Late yesterday evening (or late this morning, in Seoul) Samsung announced that it's stepped up the speed of its HBM2 memory offerings from 1.6 GT/s to 2.4 GT/s. The speed increase comes without a change in supply voltage unlike the 2.0 GT/s intermediate step that required 1.35 V rather than the standard 1.2 V input. Samsung has apparently decided to call the new memory Aquabolt.

The step up in speed results in a total bandwidth per package of 307 GB/s. As Samsung points out, using four Aquabolt HBM2 packages would result in a total bandwidth of about 1.2 TB/s. The company says it worked hard to overcome challenges in managing both clock skews and thermal output with the new packages. Samsung also says that the new Aquabolt packages are also more durable than the last-generation chips as a result of the improved design.

The 50% jump in transfer rate would boost a Vega M GH chip from 205 GB/s to the aforementioned 307 GB/s—nearly matching a brand-new Xbox One X. The press release doesn't actually say when Aquabolt will be available to vendors, but it does say that the new memory is "in mass production." We'd take that to mean that we could see products using these parts later this year.

Speaking of the previous-generation offerings, along with this announcement comes the interesting tidbit that Samsung's previous HBM2 was called Flarebolt. The earliest mention we can find of that name is a US trademark filing from December 12 last year, so it's probably safe to say that Samsung has only recently decided to start branding its HBM offerings. Whatever the names, we're always happy to see faster RAM.

    Aquabolt? [url=https://wow.gamepedia.com/Nalash_Verdantis<]WOW Mists of Panderia expansion?[/url<] Maybe the next model will be keg smash.

      It’s better than Taserface.

    An oversized tile that looked like that die would make my bathroom shiny and bright again.
    Edit: At 307GB/s, one 8-high stack would make a very nice Vega Polaris 10 replacement. Doubt AMD would do it on the desktop, though…

    So we should expect HBM3 to be named Usain ?

      I like it, but they might be working their way through elementals first. Next up: Terrabolt

      And they may decide to do an overclockers edition with higher voltage and call it Armstrong while they’re at it.

    Hopefully it can be used on Vega sometime. Tests have shown good improvements with mem OC, and lower voltage would help marginally with power balance. I wonder if sturdier layout would improve heatsink situation. Better thermals would be big plus, HBM2 OC headroom is highly temperature sensitive.

      I have always wondered if vega clocks were held back by the interposer.

    Is that like a frost bolt under heavy thermal constraints?

    Sounds like something Aquaman would throw at an errant octopus.

      I used to be bandwidth constrained, but then I took an Aquabolt to the knee?

        • NTMBK
        • 2 years ago

        Does an octopus have 8 knees, or no knees?

          • DPete27

          2 knees. The other 6 are elbows.

          I’m not sure, but I know sea urchin have Uni.

      Or a fast-acting and poorly named diuretic.

      I used to have trouble “going”, but then I took an Aquabolt, and now the pipes are flowing free and clear!

    IIRC the initial batches of HBM2 that actually came to market were somewhat slower than what was initially expected, which was probably a manufacturing decision based on product yield to get the products out the door.

    This appears to be a refined version of HBM2 just like we see refined versions of DDR4 & GDDR5/5X that are released after earlier and somewhat slower versions have hit the market.

      I think the more interesting thing here is the physical modifications to the HBM packaging (evidently more “stout” base layers and more thermal bumps for heat dissipation.) I didn’t even know there were those kinds of issues with earlier HBM/2 modules.
