Samsung has announced the mass production of 16 Gb GDDR6 SDRAM chips with a higher-than-expected pin speed. The chips could see use in upcoming graphics cards that are not equipped with High Bandwidth Memory:
Samsung has beaten SK Hynix and Micron to be the first to mass produce GDDR6 memory chips. Samsung's 16Gb (2GB) chips are fabricated on a 10nm process and run at 1.35V. The new chips have a whopping 18Gb/s pin speed and will be able to reach a transfer rate of 72GB/s. Samsung's current 8Gb (1GB) GDDR5 memory chips, besides having half the density, work at 1.55V with up to 9Gb/s pin speeds. In a pre-CES 2018 press release, Samsung briefly mentioned the impending release of these chips. However, the speed on release is significantly faster than the earlier stated 16Gb/s pin speed and 64GB/s transfer rate.
18 Gbps exceeds what the JEDEC standard calls for.

- I was referring to exceeding JEDEC. Are the manufacturers going to go along, or just keep that for the OC cards?
- "Overkill" bandwidth is just bandwidth is just bandwidth waiting for the next gen part to use/waste it. The question could be rephrased as "is HBMx going to kill GDDR6, or just prevent 7 from existing?"
- Coins are hurting this minute, but may just bubble again next week. And miners love the coins that can't be taken over (yet) by ASICs. When the bubble bursts, GPU makers will hurt from the drop in demand and the flood of used gear. In the meantime, I'm glad I'm not looking to upgrade.

I think JEDEC standards have been flaunted before (example: modules advertised as DDR4-4400, DDR4-4600, or DDR4-4800). If Nvidia or AMD can get 18 Gbps per pin memory to work with their GPUs, they will use it.
I don't have a good track record about HBM predictions (I thought it would sweep GDDRn away). I think the story lets us know that HBM 2/3 will not kill GDDR6 but will co-exist. Nobody knows about GDDR7.
