SK Hynix has showcased their first GDDR6 wafers and specifications at GTC 2017, revealing up to a 2x increase in memory bandwidth when compared to GDDR5 while also decreasing power consumption and offering higher storage densities. 
 
GDDR6 will offer a 10% decrease in power consumption when compared to GDDR5, which when combined with the new standard's increased bandwidth will allow GDDR6 to offer huge power saving per unit of data. 
 
Nvidia has made no showing of HBM2 or any other high bandwidth memory standard at GTC 2017, which makes it seem unlikely that Nvidia is pursuing the of any memory standard other than GDDR6 in the near future. Will Volta be using GDDR6 exclusively?

The GDDR6 modules shown at GTC come with a capacity of 8Gb (1GB) per module, though GDDR6 will also come in capacities of 16Gb (2GB) per module. This will allow GDDR6-based GPUs to offer higher memory capacities, as well as offer more memory bandwidth.  

These changed will effectively allow GDDR6 to offer te same memory bandwidth and capacities as GDDR5 while using half the memory bus size on the GPU-side and half the GDDR6 memory chips. This means that a GPU with a 128-bit memory bus with GDDR6 can offer the same performance as a GPU using a 256-bit memory bus and GDDR5. 

These changes will allow mid-range GPUs to be created with a much less complex memory sub-system, while also offering reduced power draw and cost due to reduced power requirements and component count.

It looks like at launch GDDR6 will offer maximum bandwidths of 16Gbps, with lower end models likely coming with bandwidths of 12-15Gbps, which is still faster than the 11.4Gbps GDDR5X modules used in the Nvidia Titan Xp.

How nice would a 384 bit bus be for 768 Gbps... Expensive though so that may be limited to the inevitable titan, Ti and quadro parts with everything enthusiast below with a 256 bus? I also read it's named the 3000 series for some odd reason? Never understood the digit skipping.Quote
