Samsung’s confirmed its upcoming GDDR6 memory will be faster than previously anticipated, clocking in at 16Gb/s data rate. Originally, when Samsung revealed its GDDR6 memory last year, it was expected to top out at 14 Gbps. yet now, as it enters mass production, Samsung has bumped up its own targets to 16 Gb/s.

“The fastest and lowest-power DRAM for next generation, graphics-intensive applications,” teases Samsung in a new statement. “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.” I have to say that little DVD fact is kind of blowing my mind. Now all I can do is look at my USB cables and scowl. It should mean 4K bandwidth is a breeze for GPUs which utilise it.

That brings Samsung’s GDDR6 high-speed video memory up into line with Micron’s upcoming GDDR6 memory, and indeed its experimental 16Gb/s GDDR5X. The difference here is that Samsung has achieved it on a single 16GB GDDR6 memory die, doubling the density of its competitors. It means the standard we can expect from GDDR6 is 16Gb/s across the board, compared to a peak of 10Gb/s with GDDR5 and 11Gb/s for the GDDR5X memory used on the GeForce GTX 1080 Ti.

As for how this stacks up in the real world, GDDR6 on a 384-bit memory interface could achieve 768Gb/s memory bandwidth. On the Geforce GTX 1080 Ti with its 352-bit memory interface, memory bandwidth hits 484 GB/s. That’s a 58% increase in memory bandwidth.

From the looks of things, GDDR6 is going to debut on the next generation of graphics cards from both Nvidia and AMD. A recent rumour suggested Nvidia could be launching GeForce Ampere (or Volta) as early as March 2018, complete with GDDR6 memory as standard.
