SK Hynix is almost ready to produce GDDR6 memory with higher than expected per-pin bandwidth:

In a surprising move, SK Hynix has announced its first memory chips based on the yet-unpublished GDDR6 standard. The new DRAM devices for video cards have capacity of 8 Gb and run at 16 Gbps per pin data rate, which is significantly higher than both standard GDDR5 and Micron's unique GDDR5X format. SK Hynix plans to produce its GDDR6 ICs in volume by early 2018.

GDDR5 memory has been used for top-of-the-range video cards for over seven years, since summer 2008 to present. Throughout its active lifespan, GDDR5 increased its data rate by over two times, from 3.6 Gbps to 9 Gbps, whereas its per chip capacities increased by 16 times from 512 Mb to 8 Gb. In fact, numerous high-end graphics cards, such as NVIDIA's GeForce GTX 1060 and 1070, still rely on the GDDR5 technology, which is not going anywhere even after the launch of Micron's GDDR5X with up to 12 Gbps data rate per pin in 2016. As it appears, GDDR6 will be used for high-end graphics cards starting in 2018, just two years after the introduction of GDDR5X.

    I recall that SK Hynix was one of the manufacturers whose DDR4 modules were much more resistant to Rowhammer attacks [soylentnews.org] than those from Crucial/Micron, based upon test results from thirdio.com [thirdio.com]. (G.Skill was the other manufacturer with highly resistant DDR4 modules.)

    Some of their fancy DDR6 memory might go well with the card needed to drive my future Facebook-branded face mask [oculus.com].
