If Intel and others could even get 7nm quality chips working that would likely be good enough for the foreseeable future. I really want to see a proper head to head of ARM vs x86 with chips at the same fabrication scale - right now part of the reason ARM (and apples new CPU's) are leagues ahead is also just that they are on a different manufacturing process. A modern AMD processor on identical scales might actually be (somewhat) close to the power efficiency of ARM. I'm sure it would still lose but it would be interesting.
