Samsung announces 16Gb GDDR6 memory

Running at 16Gbps

Inside Samsung’s bragging announcement that it managed to sweep a total of 36 CES 2018 innovation awards, is the announcement of its “fastest and lowest power DRAM”, a 16Gb GDDR6 memory running at 16Gbps.

According to brief statement, Samsung says its GDDR6 is running at 16Gbps with 64GB/s data I/O bandwidth. Operating at 1.35V, it also offers significant advantages compared to the GDDR5 memory which usually runs at 1.5V and offer speeds of around 8Gbps.

According to what we know GDDR5 does work at 1.5V, but also supports 1.35V in low-power operation, with a slightly lower rata rate and has dynamic voltage scaling with on-the-fly change between 1.5V and 1.35V.

Micron’s own GDDR5X specification shows that it is quite similar to the announced GDDR6 memory from Samsung, with a slightly lower 8Gb density. It also works at 1.35V and has a separate 1.8V supply but offers significant improvement in data rates, reaching up to 16Gbps.

It will be quite interesting to see the full specification of Samsung’s announced 16Gb GDDR6 memory but guess we will hear about it at CES 2018 show. We also expect both Micron and SK Hynix to announce GDDR6 memory by the end of this year or early next year.
