AT GTC (GPU Technology Conference) a company named Sk Hynix displayed their new memory technology. Which is the new GDDR6 memory standard, that will be used on the upcoming Nvidia GPU. Which will include the VOLTA architecture, that will arrive next year 2018.

Currently Nvidia is using their new GDDR5X memory standard on their high end graphics cards. Which includes the recently launched GTX 1080, GTX 1080Ti and the GTX Titan XP 2017. Aside from that Nvidia also uses HBM2 memory as well, something that AMD will also be introducing with their VEGA GPU. Though right now only the Tesla P100 GPU from Nvidia is using the HBM2 memory standard.

There are two main differences between GDDR5X and the new GDDR6. Where the upcoming GDDR6 will be faster in memory speed as well as power efficient. While the new GDDR6 memory will be available with up to 16GB of VRAM on board. That will be running at a speed of 16Gbps, much faster than the 11Gbps speed of the current GDDR5X memory standard. Where it is able to do all that by using 10% less power.

Nvidia also showed two different Volta cards, where one came with 256-bit memory bus. While the other was being offered with 384-bit memory bus. Though if Nvidia went with the 384-bit memory bus. Then we are looking at a memory bandwidth of 768Gbps. Which is higher than what the upcoming AMD VEGA has to offer at 512Gbps. While the 256-bit memory bus on Nvidia VOLTA provides a memory bandwidth of 512Gbps.

We would certainly need the extra VRAM in the future. As now people are interested in how games would run and look at 8k resolution. Aside from that Nvidia also has to look over its shoulder, as AMD VEGA is just around the corner. Where  to retain its customer, Nvidia has to come up with something better than their current Pascal lineup.
