Nah... back then single thread performance mattered a lot. Today most users can do most of their work on something with the performance of an iPad.

Apple will not suffer in 2020 from having lower performance than intel. It wont matter. Form factor, screen quality, memory speed, memory size, touch pad, battery life etc will matter so much more.

Multi threading is also so much more common on pro app which require performance. They can just match intel by using more cores. ARM is way cheaper than intel so I don't see how they can lose this game. PPC was an entirely different world.
