SK Hynix has shown their first GDDR6 wafers and specifications at GTC 2017
 Â
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. Â
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.Â
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.Â
Â
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.Â
