A few weeks ago, we’ve written an article regarding Samsung’s plans to mass produce its GDDR6 memory module. This time round, however, Samsung’s competitor, SK hynix, has also announced its GDDR6 memory controller; but unlike Samsung, SK hynix’s GDDR6 DRAM is apparently readily available.
To be more specific, SK hynix has made two different variants of its GDDR6 memory controller available. Their part numbers are listed as H56C8H24MJR-S2C and H56C8H24MJR-S0C. In addition, there are three different types of frequency speeds: 10Gbps, 12Gbps, and 14Gbps. In comparison, Samsung’s recently announced GDDR6 memory controller has a slightly faster pin speed of 18Gbps.
Currently, the fastest GDDR memory controller (GDDR5X) is found inside the Nvidia’s Titan Xp; its has a frequency speed of 11.4Gbps. Knowing how both SK hynix and Samsung’s upcoming memory controllers are significantly faster than what is currently offered today, consumers can most definitely expect future graphics cards to come with huge improvements in terms of memory bandwidth speeds and power efficiency.
Despite this, it’s still not known when we’ll actually get to see GDDR6-equipped graphics cards from Nvidia and AMD. One has to also remember that GDDR6 also faces competition from another memory controller called HBM2 – one which Samsung is also mass producing at the moment.
