This year is shaping up to be a good year for memory with the promise of 3D XPoint (Intel/Micron), HBM2 (SK Hynix and Samsung), and now GDDR6 graphics memory from Micron launching this year. While GDDR6 was originally planned to be launched next year, Micron recently announced its intentions to start producing the memory chips by the later half of 2017 which would put it much earlier than previously expected.
Computer World reports that Micron is citing the rise of e-sports and gaming driving the computer market that now sees three year upgrade cycles rather than five year cycles (I am not sure how accurate that is, however as it seems like PCs are actually lasting longer between upgrade as far as relevance but i digress) as the primary reason for shifting GDDR6 production into high gear and moving up the launch window. The company expects the e-sports market to grow to 500 million fans by 2020, and it is a growing market that Micron wants to stay relevant in.
If you missed our previous coverage, GDDR6 is the successor to GDDR5 and offers twice the bandwidth at 16 Gb/s (gigabits per second) per die. It is also faster than GDDR5X (12 Gb/s) and uses 20% less power which the gaming laptop market will appreciate. HBM2 still holds the bandwidth crown though as it offers 256 GB/s per stack and up to 1TB/s with four stacks connected to a GPU on package.
As such, High Bandwidth Memory (HBM2 and then HBM3) will power the high end gaming and professional graphics cards while GDDR6 will become the memory used for mid range cards and GDDR5X (which is actually capable of going faster but will likely not be pushed much past 12 Gbps after all if GDDR6 does come out this soon) will replace GDDR5 on most if not all of the lower end products.
I am not sure if Micron’s reasoning of e-sports, faster upgrade cycles, and VR being the motivating factor(s) to ramping up production early is sound or not, but I will certainly take the faster memory coming out sooner rather than later! Depending on exactly when in 2017 the chips start rolling off the fabs, we could see graphics cards using the new memory technology as soon as early 2018 (just in time for CES announcements? oh boy I can see the PR flooding in already! hehe).
Will Samsung change course as well and try for a 2017 release for its GDDR6 memory as well?
Are you ready for GDDR6?
