There is a danger here though that people equate market strategy to tech/R&D development progress. AMD managed to successfully catch Intel wrong footed in their product execution cycle but it doesn't mean - as some try to make out - that Intel has fallen behind and will be playing catch up on some of the tech that AMD have put into their CPUs, etc.
Oh I quite disagree on this. Intel won't have their new architecture ready before 2020 (the earliest). Even then, there's a risk their new architecture may not perform as well as they hope.
Right now, the fact that they have a process advantage saves them. The 10nm chips will give Intel a respite at the end of the year. But come 2019 they will be in trouble again with the next iteration of Zen. The 7nm GloFo process will be equal (expectations are that it will actually be marginally better) to Intel's 10nm, so no more process advantage. It is very likely the crown for highest clock will go to AMD and then there's still the power efficiency and the cost/scaling of the CCX approach. I expect Intel will bleed some more due to all this...
