GDDR6 Slated for Next-Gen nVidia GPUs, Mass Production in 3 Months

By Published March 28, 2018 at 12:34 am

At GTC 2018, we learned that SK Hynix’s GDDR6 memory is bound for mass production in 3 months, and will be featured on several upcoming nVidia products. Some of these include autonomous vehicle components, but we also learned that we should expect GDDR6 on most, if not all, of nVidia’s upcoming gaming architecture cards.

Given a mass production timeline of June-July for GDDR6 from SK Hynix, assuming Hynix is a launch-day memory provider, we can expect next-generation GPUs to become available after this timeframe. There still needs to be enough time to mount the memory to the boards, after all. We don’t have a hard date for when the next-generation GPU lineup will ship, but from this information, we can assume it’s at least 3 months away -- possibly more. Basically, what we know is that, assuming Hynix is a launch vendor, new GPUs are nebulously >3 months away.


Also of interest, we learned that GDDR6 will be about 20% more expensive in manufacturer cost than GDDR5 at launch. That cost will obviously be passed on from board vendors to consumers. GDDR6 should come down to +15% and +10% over time, as mass production ramps and overtakes GDDR5 production lines in the factories.

This is all assuming that our contact at the show provided us accurate information, granted. We presently have no reason to doubt the information we were provided. Straight from the source, Hynix enters MP on GDDR6 within 3 months. GDDR6 will also be on future nVidia GPUs. The big question is when those come – we’d peg it as July or later, right now. 2H18, hopefully. This enters territory of speculation and is not as informed as other information in this post, but the RTX Volta support addition to Unreal Engine 4.20, due in July, plus MP of GDDR6 in June-July, we think indicates ramp-up for a GPU launch sometime thereafter. NVidia has previously launched GPUs toward the end of summer.

As for other specifications, Hynix’s GDDR6 will run a 180 ball-grid array from GDDR5’s 170 BGA, enabling greater throughput from the extra pins. Hynix’s GDDR6 will operate upwards of 16Gb/s and ship in 8Gb and 16Gb densities, up from 8Gb densities only on GDDR5. Hynix’s GDDR6 should pull 1.35V and operate at lower power consumption targets, but we don’t have exact numbers right now.

That’s what we’ve got for now. Note that these are facts gathered by GamersNexus at GTC 2018.

Steve started GamersNexus back when it was just a cool name, and now it's grown into an expansive website with an overwhelming amount of features. He recalls his first difficult decision with GN's direction: "I didn't know whether or not I wanted 'Gamers' to have a possessive apostrophe -- I mean, grammatically it should, but I didn't like it in the name. It was ugly. I also had people who were typing apostrophes into the address bar - sigh. It made sense to just leave it as 'Gamers.'"

First world problems, Steve. First world problems.
