Nice, but we're years away from seeing that in a miner.
Or it becoming worthwhile for any manufacturer to stump up what, $10M to have a go at 7nm.
Meh, people have been claiming this since BTC asics first showed up. It took just over 3 years to go from 130nm to 14/16nm. This space is so full of retards I think it's quite possible someone is going to start working on 7nm as soon as tools are available.
That's a terrible example. How long did it take us to actually release 16nm after it was 'available' and even after everyone announced their chips, 18 months?
A year max.
It was late 2014 when companies started announcing chips to arrive early 2015. It was May 2016 by the time we had public delivered 14/16nm.
