The upcoming GeForce GTX graphics cards coming from NVIDIA based on the “Volta” architecture could indeed feature GDDR6 memory. This is according to a supply deal that NVIDIA has stuck with SK Hynix. This deal caused SK Hynix’s stock price to surge 6%.
We do not know if GDDR6 will be deployed on all “Volta” SKUs, or if it will be like GDDR5X, where it will only be available on a small number of high-end SKUs.
SK Hynix has 8 Gb (1 GB) GDDR6 memory chips supporting speeds of up to 14 Gbps at 1.35V, and up to 12 Gbps at 1.25V. Since NVIDIA has GDDR5X running at 11 Gbps, the could use it as a cheaper option, or opt for the faster GDDR6.
