SK Hynix, the other Korean DRAM and NAND flash giant than Samsung, updated its DRAM product catalog to reflect immediate availability of its 8-gigabit (1 GB) GDDR6 memory chips. The company is selling four SKUs, part "H56C8H24MJR-S2C" in 14 Gbps and 12 Gbps variants; and part "H56C8H24MJR-S0C" in 12 Gbps and 10 Gbps variants. The -S2C chips are more energy efficient, in achieving 14 Gbps at 1.35V and 12 Gbps at 1.25V; while the -S0C achieves 12 Gbps at 1.35V, and 10 Gbps at 1.25V. Unless NVIDIA decides that the GTX 1080-successor should feature 16 GB of memory, the company could be in the market for 8 Gb GDDR6 chips.

Meanwhile, rival Samsung announced that it began mass-production of 16 Gb (2 GB) GDDR6 memory chips, which should enable 16 GB of memory across a 256-bit memory interface, or 8 GB over a 128-bit interface. Samsung's latest chips not only have double the density as SK Hynix's, but also tick faster, at 18 Gbps, with a voltage of 1.35V. It is widely expected that GDDR6 will be the dominant memory standard for entry, mainstream, and even high-end graphics cards, which launch through 2018-19. NVIDIA is expected this year to launch its new "Volta" graphics architecture across various consumer-graphics market-segments.
