SK Hynix Marks its 8Gb GDDR6 Memory Chips "Available" in Latest Catalog Update

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.

16Gb would be overkill and pricing to skyrocket in this cryptomining insanity, not that gaming is very sane. 1180 8G 14 is more likely, 12 for the 70's. However 40% faster than GTX 1070 and double the gram capacity is good for SLI.Yeah.

2GB is too much for you ? What world are you living in ?:laugh:

don't forget the xx80 TI. I would be severly disappointed if not even the xx80s got 16GB :(

Well they can also just use fewer 2GB chips. It doesent have to be 12x2GB=24GB. It could be 4x2GB=8GB or 8x2GB for 16GB. I doubt we will see over 16GB total in consumer cards. Unless Nvidia introduces a GDDR6 based Titan that has 24GB. Hell if they wanted to they could put 12 chips on each side of the PCB like old days and achieve 48GB. At speed quoted by Samsung nearly 900GB/s is nothing to sneeze at. Even current gen HBM2 is barely faster. Tho yes Samsung did also announce faster HBM2 variant able to achieve 1,2TB/s with four stacks but my bet is that is worstation only.
