SK Hynix will differ from Samsung's upcoming GDDR6 with only up to 14Gbps of bandwidth, compared to the maximum 18Gbps on offer from Samsung. Still, 14Gbps offers up to a huge 768GB/sec of memory bandwidth given a 384-bit memory bus, which sounds suspiciously like what we'd find on a next-gen TITAN X from NVIDIA.
