"GMO’s 7nm ASIC Chips
The design logic of the 7nm chip has already been completed
Which is a long EXPEN$IVE way away from having working engineering samples to prove working silicon, much less PRODUCTION silicon.
Do I expect someone (probably more than one someone) to come out with an S9 beater on the 7/10 nm node? YES.
Do I expect it in 2018? Not only "NO" but "PRETTY MUCH DEFINITELY HELL NO".
Do I expect it in 2019 sometime? Probably.
Samsung appears to be in production (in small "trial proof of technology" mode) on their 10nm node, so I expect their next smartphone design will probably use a 10nm chip.
Intel has already announced production of 10nm CPUs for later this year - they HAVE been working on that longer than pretty much anyone else, so it's not a shock if they get to market first.
GF and TSMC "7nm" looks to be hitting small scale engineering proof production levels late this year, and probably won't hit full production levels for months to a year after that.
Also expect YIELDS to be very poor for the first year at least, based on experience with the LAST TWO production nodes.
Then we get to start thinking about the issue with the "next node" and both Intel and IBM stating the CURRENT node is "end of the road for pure silicon"....
