AMD has been executing well for years and the market only recently took notice. That doesn't mean Intel can't benefit as the pie gets bigger, and it doesn't mean 10nm has to be a death knell for Intel.
Apple released a new chip to its own fanfare, but unless you bought an M1 device or made a shopping appointment in an Apple Store (they wouldn't even let me walk over to the MacBook when I went to pick up an online order), you don't have much reliable information outside of what some tech journalists have posted on the internet.
AMD is doing well indeed.
AWS and others are trying to push ARM because of better performance/watt in datacenters. Exactly the same metric for laptops.
They just have. The M1 range are $3000-$4000 worth of computer starting at around $1000.
The short term threat to Intel is from AMD.
The long term threat is proliferation of 5nm tech and design lapses from Intel side.
Apple is not a competition to Intel, atleast directly.
Macs will never be a mass market product, unless Apple slashes prices. But that is not going to happen.
What will happen is Intel will pull through, for another decade or so, with mediocre but cheap processors, supplying mass market volumes, with AMD being a tough competitor.
