NVIDIA GeForce "Volta" Graphics Cards to Feature GDDR6 Memory According to SK Hynix Deal
NVIDIA's upcoming GeForce GTX graphics cards based on the "Volta" architecture, could feature GDDR6 memory, according to a supply deal SK Hynix struck with NVIDIA, resulting in the Korean memory manufacturer's stock price surging by 6 percent. It's not known if GDDR6 will be deployed on all SKUs, or if like GDDR5X, it will be exclusive to a handful high-end SKUs. The latest version of SK Hynix memory catalogue points to an 8 Gb (1 GB) GDDR6 memory chip supporting speeds of up to 14 Gbps at 1.35V, and up to 12 Gbps at 1.25V.
Considering NVIDIA already got GDDR5X to run at 11 Gbps, it could choose the faster option. Memory remains a cause for concern. If 8 Gb is the densest chip from SK Hynix, then the fabled "GV104" (GP104-successor), which could likely feature a 256-bit wide memory interface, will only feature up to 8 GB of memory, precluding the unlikely (and costly) option of piggy-backing chips to achieve 16 GB.

GTX 560 ti 1GB 256bit gf114 (8*1Gb)
GTX 680 2GB 256bit gk104 (8*2Gb)(/GTX 680 4GB )
GTX 770 2GB 256bit gk104 (8*2Gb)(/GTX 770 4GB)
GTX 980 4GB 256bit gm204 (8*4Gb)
GTX 1080 8GB 256bit gp104 (8*8Gb)
So nvidia have been doubling the memory amount to every new arch. If they are continuing doing that gtx 1180 would be 256bit bus with 16GB of memory(8*16Gb). Which would not be surprising me, while remembering from the past:
gtx580 1.5GB-> gtx680 2GB
gtx780 ti 3GB -> gtx980 4GB
gtx980ti 6GB -> gtx1080 8GB
But will they actually need to do that, is the other question.
