Who Could Be The Potential Customers of GDDR6 Memory?

When talking about potential customers, the most obvious one is NVIDIA. It was already confirmed that NVIDIA Volta consumer GPUs will be utilizing the GDDR6 memory interface as pointed by the production and release plans of consumer Volta graphics cards which falls in 1H of 2018. It’s worth noting that Micron and Samsung have been key partners in providing NVIDIA with their respective DRAM offerings. NVIDIA was and remains to be the first and only customer who utilized their G5X memory standard and will continue their collaboration with Volta and GDDR6. Similarly, Samsung’s HBM2 technology has been a key enabler for Volta based Tesla V100 GPUs which started shipping to customers in the previous quarter.

AMD on the other hand may still carry on with HBM2 on their Vega cards while a potential entry or budget tier Vega chip may utilize the cheaper and upgraded memory interface, possibly explaining the delay of Vega 11. SK Hynix, a key partner of AMD in development of HBM DRAM is also going to offer GDDR6 memory and AMD could utilize that.


A third entrant in the GPU industry, Intel, who recently hired AMD’s ex-graphics technology head, Raja Koduri, plans on developing their own discrete GPUs. While they are years away from producing a competitive, high-end discrete graphics, GDDR6 is here to stay for several years and Intel could tap on the new technology to provide consumers a range of competitive GPU based solutions. There’s a ton of announcements expected at CES 2018 and we hope to learn more on GDDR6 during the event, especially at NVIDIA’s CES 2018 keynote.
