The SK Hynix product portfolio gets GDDR6 DRAM-- described by the company as "the world's fastest 2Znm 8Gb (Gigabit) GDDR6 (Graphics DDR6) DRAM" designed for high-end graphics card use.
The 20nm 8Gb chips operate at 16Gbps per pin, an industry record. SK Hynix provides a performance example of a graphics card with a 384-bit memory bus equipped with GDDR6, offering a bandwidth of up to 768GBbps. In comparis, an Nvidia GeForce GTX 1080 Ti equipped with GDDR5X has a bandwidth of under 500GBps.
SK Hynix adds it is "collaborating with a core graphics chipset client to timely mass produce the GDDR6 for the upcoming market demands." The launch of high-end graphics cards armed with GDDR6 RAM is expected for Q1 2018, and the technology should also find use in hardware powering AI and self-driving cars, among other applications.
The GDDR6 standard is still being drafted by JEDEC, but it should offer twice the speeds of GDDR5 while operating at 10% lower voltage. SK Hynix plans to "speedily substitute GDDR5 and GDDR5X" with new GDDR6 chips, while competitors Samsung and Micron should start production of GDDR6 modules by end 2017.
