However this is only at 10mm. If Intel gets on 5nm, AMD (and Apple) has a problem. They are in the spotlight now because Intel their manufacturing has been crap for the last few years, unable to move past 14mm.
Intel can easily be back if they outsource their manufacturing to Asia where all the expertise of producing chips is nowadays (even Samsung is also at 5mm).
From what I understand, Intel's 10nm is roughly equivalent to TSMC's 7nm, so the difference is not as large as it sounds. Besides, Intel is currently years behind the schedule, what are the chances that they manage to get the next node production-ready any time soon? It took them four years to make 10nm work reasonably well, and still, their CPUs are as hot as ever (mobile Tiger Lake actually rises the TDP on the high-end models!). Plus, they still seem have yield issues, as their desktop is still on 14nm...
The reality of the situation is that TSMC has the most advanced process right now, and everyone else plays catch up. Samsung's 5nm is also inferior to TSMC's 5nm (in fact,
it seems worse than TSMC's 7nm). Given the fact that Apple has tons of cash and can win any foundry bidding war, they will have access to most advanced processes going forward, giving them a decisive advantage for the foreseeable time.
And besides, even if Intel manages to close the process gap, their power-efficiency is still atrocious compared to Apple's designs.
