SK海力士引入GDDR6：将在2018年初被高端显卡采用

SK海力士在4月24日宣布引入GDDR6显存，计划量产并将在2018年初用于高端显卡。

作为下代JEDEC标准的GDDR6将会是目前GDDR5和GDDR5X的替代者，这两种显存均基于DDR3技术（G5X有DDR和QDR模式，GD5只有DDR模式），GDDR6则基于DDR4。

这款目前世界最快的2Znm 8Gb GDDR6运行在16Gbps的频率，远高于目前的GDDR5 9Gbps，更比目前G5X 11.4Gbps（Titan Xp）高出40%。

搭配384bit位宽可达到768GB/s的带宽，目前Titan Xp搭配的11.4Gbps G5X也只有548GB/s。

相较于目前的GDDR5/5X，GDDR6的运行电压降低了10%，功耗同时也会降低。

GDDR6被看做新兴产业如AI、VR、自动驾驶、4K以上高分辨率显示等的必要内存解决方案，据Gartner，显卡的平均显存容量今年将达到2.2GB，预计在2021年达4.1GB，复合年均增长率17%。

SK Hynix Inc. Introduces Industry’s Fastest 8Gb Graphics DRAM (GDDR6)
2017.04.23

Seoul, April 23, 2017 ? SK Hynix Inc. (or ‘the Company’, www.skhynix.com) today introduced the world’s fastest 2Znm 8Gb(Gigabit) GDDR6(Graphics DDR6) DRAM. The product operates with an I/O data rate of 16Gbps(Gigabits per second) 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(Gigabytes) of graphics data per second. SK Hynix has been planning to mass produce the product for a 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 according to what graphics cards command in PCs, workstations, video players and high performance gaming machines. Especially, GDDR6 is a next generation graphics solution under development of standards at JEDEC, which runs twice as fast as GDDR5 having 10% lower operation voltage. As a result, it is expected to speedily substitute for GDDR5 and GDDR5X. SK Hynix has been collaborating with a core graphics chipset client to timely mass produce the GDDR6 for the upcoming market demands.
 
“With the introduction of this industry’s fastest GDDR6, SK Hynix will actively respond to high quality, high performance graphics memory solutions market” said senior vice president Jonghoon Oh, the Head of DRAM Product Development Division. “The Company would help our clients enhance their performance of high-end graphics cards” he added.
 
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%.
