GDDR5X has been the high-end memory for some time now. We have seen its magic in the high-end GPUs like the GTX 1080 as well as the GTX 1080 Ti. As AMD gets ready to introduce HMB2 memory in the AMD Radeon RX Vega series, Nvidia will be looking into using GDDR6 memory. This, however, is not something that we will be able to see this year.
GDDR6 will be able to provide 16GB per second of bandwidth, compared to the GTX 1080 and 1080 Ti that are capable of 11 GB per second, which is a drastic increase in performance. Reports claim that the new memory will be coming out in GPUs in early 2018 which might be a bummer for the people that were waiting for the GTX 20 series GPUs from Nvidia that will be based on volta.
If GDDR6 memory will be coming out next year then it is possible that the next-gen Nvidia GPUs will not feature this new memory and will come with GDDR5X memory instead. The mid-range GPUs could still feature GDDR5. That, however, is not a confirmed thing yet as Nvidia might have already got the new memory architecture for its Volta GPUs expected to come later this year.
According to the official press release:
“SK Hynix Inc.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”
GDDR6 memory will replace GDDR5 and GDDR5X and Nvidia will be the biggest client as far as I can tell. It will be interesting to see what kind of performance this new memory will enable in games next year. You can check out the full press release here.
Let us know what do you think about GDDR6 memory and whether or not you would consider buying a new GPU that features this new memory.
