SK hynix Q2 products list includes GDDR6 and HBM2
Graphics RAM chips availability scheduled for Q4 2017 and Q2 2017 respectively.
- SK hynix's Q2 2017 databook, reported 16 May 2017, lists two 8Gb GDDR6 parts (14.0Gbps and 12.0Gbps) shipping to manufacturers in Q4 2017, in line with Samsung and Micron[1]
- HBM2 is listed as available in Q2 2017, with AMD Vega cards reported to launch at the end of May and be available from 5 June[1]
- Nvidia will use some HBM2 in its Tesla V100 (Volta), and GDDR6 is thought to reach some Nvidia Volta consumer cards[1]
Notable features
- SK hynix had introduced its 20nm 8Gb GDDR6 the previous month, claimed to run up to 16Gbps per pin, an industry record, for theoretical card bandwidth up to 768GBps[1]
- SK hynix expects GDDR6 to supplant GDDR5 and GDDR5X in faster graphics cards; for comparison, Nvidia's Titan Xp reaches 547.7GB/s with 12GB of GDDR5X on a 384-bit bus, against 768GB/s for GDDR6 on the same bus width[5]
- SK hynix also sees GDDR6 playing a role in artificial intelligence, virtual reality, self-driving cars and 4K Ultra HD[5]
- An earlier catalog in January 2017 listed a single 1.6 Gbps HBM2 part (4GB, 4-Hi, 204.8 GB/s) with no 2.0 Gbps variant[3]

WCCFTech's headline notes HBM2 "Availability in Q1 2017," which is earlier than the pin's stated Q2 2017/30 June 2017 date - a discrepancy worth flagging - and the page itself returned a 403 error so the full context could not be verified.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
