There's a very, very big difference between "rolling out 14nm" with unknown yields, performance, etc. Vs Intel's venerable 14nm process.

Intel is Intel, as unhelpful as that statement is. So these guys are starting on 14nm, while others are pushing ahead to 5 and below. Sure it'll work, but I don't find that competitive in an already crowded smartphone market in the next 2 years.

They've been rolling it out since 2016, better wait until their product actually appears.
