About Intel's troubles with 10nm and below... I would say, nobody here has complete insight. And so, we're all allowed to guess and make conclusions from what we can read in media.
I wouldn't be surprised if part of the reason why Intel took extra risks with process development was to give AMD a chance to survive so Intel could avoid becoming a strictly regulated monopoly after AMD's bankruptcy.
-that is HIGHLY unbelievable.
If that would be the case, then Intel would start showing his "actual" progress by now -after certain reputation was lost, Apple decided to ditch Intel, few CEO's were replaced, etc.
Of course, it's important for Intel that competition is alive (avoiding monopoly), but if AMD would start to have problems (at that time), there are "other ways" how to "help" AMD to start breathing again -I'm quite sure Intel knows that.
My impression is, Intel made few strategic mistakes in past (maybe they invested more into keeping stock holders happy, than into technology development). Time goes very fast when talking about technology and I think Intel was caught at taking a nap, while others were working.
Don't get me wrong, it's not that I would think it's over with Intel -far from that!! I just think Intel will remember that and learn a lesson.
Just sharing my thoughts.
