Samsung recently released some information regarding CES awards, in this piece of information, a snippet of an award pointing towards their GDDR6 memory was found. We filtered some of the text that includes some specifications and technology used in the memory.
Samsung 16Gb GDDR6 Memory – The fastest and lowest-power DRAM for next generation, graphics-intensive applications. It processes images and video at 16Gbps with 64GB/s data I/O bandwidth, which is equivalent to transferring approximately 12 full-HD DVDs (5GB equivalent) per second. The new DRAM can operate at 1.35 volts, offering further advantages over today’s graphics memory that uses 1.5V at only 8Gbps.
The current generation used in graphics cards maxes out at 10 Gbps on a GTX1080, but most cards use only GDDR5 instead of GDDR5X which has a bandwidth of around 7-8 Gbps. 16Gbps on the new generation would be a huge leap forward. While needing much less voltage (1.35V versus 1.5V) it can actually double the bandwidth of the commonly used GDDR5 memory.
In the meantime, GDDR5X still makes improvements and it seems like it'll likely hit an even higher bandwidth before GDDR6 gets widely implemented. Anyway, GDDR6 will have the potential to increase its bandwidth over the years. At first, it was expected that it'd hit around 14-15 Gbps, so the bandwidth that's described in this snippet is actually above expectations. While Samsung is the first to release small details about GDDR6, other companies like micron and SK Hynix are still on track as well.
