SK Hynix has announced new GDDR5 memory modules at a working frequency of 10GHz and GDDR6 memory modules at a working frequency of 14GHz, which improves their bandwidth.

The evolution in the world of hardware is constant and manufacturers want the best products to offer users the highest possible power. We have seen, for example, how NVIDIA bet on the new GDDR5X memories that worked at 11GHz for the GTX 1080 Ti and Titan Xp graphics cards, in addition to betting on updating the GTX 1060 and GTX 1080 graphics cards with the new GDDR5 memories that work at a frequency of 9GHz, all developed by SK Hynix, which is the largest manufacturer of memory chips.

We saw during GTC 2017 how Hynix showed the public the first GDDR6 memories, which were expected to be integrated into the high-end NVIDIA Volta graphics cards, in addition, shortly after we learned that the company had already started the production of HBM2 memories, memories that will be used by AMD for the Vega, but AMD Vega will carry TSMC memory. The Hynix HBM2 will be reserved for a possible NVIDIA Titan graphics card based on Volta (which seems to have been leaked), but above all it will be used for professional graphics cards such as the NVIDIA V100, a high-power graphics card that should carry 16GB HMB2.

Regarding the new SK Hynix memories, we must comment that the working frequencies of the GDDR5 and GDDR6 memories have been improved. Specifically, the frequency of the GDDR5 has increased to 10GHz and the frequencies of the GDDR6 has increased to 14GHz and as is well known, the latter still have a lot of room for improvement. The GDDR5X would not have evolution and are possibly no longer in development. It should be noted that the GDDR5s have gone from having a voltage of 1.35V in their early stages, to a voltage of 1.5V for the 8GHz version and the current 9Ghz and 10GHz, already operating at a voltage of 1.55V.
