Samsung's GDDR6 memory can now reach 16Gbps, wins CES award

  1. During last year’s Hot Chips conference, Samsung executive Jin Kim said GDDR6, a successor to the commonly used GDDR5 memory found in many GPUs, would arrive next year with a throughput of around 14Gbps. But it turns out that Samsung has spent the last 15 months speeding up the next generation of DRAM, which can now reach 16Gbps.

    The new detail was part of a Samsung announcement revealing that 36 of its products had already been recognized as Innovation Award winners ahead of January’s CES trade show. In among this year’s Galaxy phones and its 8TB NGSFF NVMe SSD is the 16Gb GDDR6, which is described as the fastest and lowest-power DRAM for graphics-intensive applications.

    It processes images and video at 16Gbps with 64GB/s data I/O bandwidth, which is equivalent to transferring approximately 12 full-HD DVDs (5GB equivalent) per second,” writes Samsung.

    For comparison, GDDR5 can reach up to 9Gbps in the newer version of the GTX 1060. And with 8GB of the refined GDDR5X, the GTX 1080 has a throughput of 10Gbps, whereas the 1080Ti flagship boasts 11GB of GDDR5X and 11Gbps.

    Not only is GDDR6 faster than today’s graphics memory, but it also consumes less power. While the current version uses 1.5V for 8Gbps GDDR5, its successor operates at just 1.35V.

    We should start seeing GDDR6 appearing in GPUs launching next year, including Nvidia’s highly anticipated Volta-based consumer cards. As noted by Wccftech, GDDR6 will come in 8Gb and 16Gb densities while the standard followed by JEDEC allows for up to 32Gb dies.

    Samsung also used the 2016 Hot Chips conference to tease the third generation of High Bandwidth Memory: HBM3. It improves the density, bandwidth, and power efficiency of HBM1 and HBM2, while being cheaper to produce. It allows GPUs with up to 64GB of memory.

    To give you an idea of how the current and upcoming memory technologies stack up against each other, check out the table below.

    As 'the mask' would say, 'Smooookin!".

    Seems 256bit memory bus cards are going to benefit with very nearly as much bandwidth as GTX1080ti and Vega 64 have now even if they only achieve the bottom line 14Gbps of GDDR6. It would be 448GB/s.

    That will be a boon for mid range parts. I would hope and expect that GTX1080 in 12 months is only equivalent to a $250 mid range card.

    This industry is crooked, and operates on the Profit-Before-Progress premise.

    I'm certain we will not see any GDDR6-based products from AMD or nVidia in 2018, both are interested in getting the maximum from the current generation, first of all. And as for nVidia, they made it clear themselves in a recent PR. At the earliest, it can only be the second iteration/revision of Volta that may feature the new memory, something like Volta Ti.

    2019 will be the year when GDDR6 products will make the scene in the graphics cards.

    On the second thought though, it is most likely that nVidia will premier GDDR6 in their new Volta-based Tesla accelerators sometimes in mid-2018, but that'll be it.

    Hynix announced 16 Gbps GDDR6 already this May.

    nVidia doesn't use memory from Hynix, only from Samsung, and probably won't use it, since Hynix is struggling to meet its manufacturing deadline, so all those were just paper announcements.

    I am fine with that, gives my 1080ti a good year or two of extended life. Will most likely upgrade on the last iteration of the 2019/2020 top-end GPUs.

    GDDR6 is coming. These companies aren't waiting for 2019, not a chance.

    Also those that love to use well nVidia said Volta or the next gpu wouldn't be anytime soon, didn't say they wouldn't be coming out in 2018. That was said months back and was simply referring to this year. I expect to see Volta or whatever they plan on calling their next gpu by Summer of 2018.

    How do you win a CES 2018 award nearly two months before CES 2018 has even taken place?
