SK Hynix Inc. said on Sunday that it has developed the fastest 2Znm 8Gb (Gigabit) GDDR6 (Graphics DDR6) DRAM. This is an upgrade of the GDDR5 boasting of faster data transferring speed than its predecessor, GDDR5 and GDDR5X.

The product operates with an I/O data rate of 16Gbps per pin, which is the industry's fastest. With a forthcoming high-end graphics card of 384-bit I/Os, this DRAM processes up to 768GB of graphics data per second. SK Hynix says it has been planning to mass produce the product for an unspecified client to release high-end graphics card by early 2018 equipped with high performance GDDR6 DRAMs.

GDDR is specialized DRAM for processing an extensive amount of graphics data quickly. Itis a next generation graphics solution under development of standards at JEDEC, which runs twice as fast as GDDR5 having 10% lower operation voltage.

GDDR6 is regarded as one of necessary memory solutions in growing industries such as AI (Artificial Intelligence), VR (Virtual Reality), self-driving cars, and high-definition displays over 4K to support their visualization. According to Gartner, average graphics DRAM density in graphics cards is to be 2.2GB this year and 4.1GB in 2021 with CAGR of 17%.

Micron is also rushing to release GDDR6 graphics memory by the end of the year.
