SK Hynix has developed an 8 Gigabit (Gb) GDDR6 DRAM that can process up to 768 Gigabytes (GB) of graphics data per second, the company announced.

The product operates with an I/O data rate of 16Gb per second per pin, two times faster than GDDR5, its predecessor.

Together with a forthcoming high-ends graphics card of 384-bit I/Os, the DRAM will process 768GB of graphic data per second.

It will be made using the 20-nanometer process.

The company will mass produce a graphics card that comes with the DRAM in 2018.

Rivals Samsung Electronics and Micron are also planning production in 2018.

Demand for GDDR out of total DRAM consumption will likely increase with the rise of artificial intelligence, higher resolution displays, and self-driving cars, where high performance GPUs will be used more to support their visualization.

According to Gartner, average graphics DRAM density in graphics cards will be 2.2GB this year and 4.1GB in 2021, growing 17 percent annually.

Earlier this month, SK Hynix announced the successful development of a 72-layer TLC 3D NAND.
