GTC 2017 - SK Hynix is displaying its next-gen GDDR6 technology at NVIDIA's GPU Technology Conference, their new memory standard that will power NVIDIA's next-gen Volta GPU architecture, with Volta-based graphics cards set to arrive in 2018.
NVIDIA is currently using various different RAM standards on their graphics cards, with their Tesla P100 graphics card using HBM2 (yes, before AMD's upcoming Radeon RX Vega), GDDR5X at 11Gbps on the TITAN Xp, Titan X(P), GeForce GTX 1080 Ti, and the new GTX 1080 11Gbps model, and then GDDR5 for the rest of its graphics cards.
SK Hynix displayed the differences between GDDR5 and GDDR6, with some huge increases in speeds and bandwidth - and up to 16Gb chips, while offering less power consumption.
GDDR6 on the other hand, is quite the leap offering 16Gbps of bandwidth over the 11Gbps on GDDR5X, at 10% lower voltage.
NVIDIA could use a 384-bit memory bus on their next-gen Volta GPU architecture and see somewhere around 768GB/sec of memory bandwidth, squishing the 512GB/sec that AMD's upcoming Radeon RX Vega is meant to be capable of. Even on a 256-bit memory bus, which is what NVIDIA will most likely use on a mid-range Volta offering, would be capable of 512GB/sec.
