The major difference between Ryzen 5000-series and Apple M1 is the former is sold out worldwide and the latter is on the shelf at every Apple Store in the world. Comparing the M1 to something that nobody can buy is dumb.
Honestly I expect the price and availability to suck big time for both. AMD can't manufacture half the volume they should to satisfy demand, while Apple is a poster child of $900 laptops costing €1000 when they finally cross the Atlantic long after release.
"Available at an Apple store" might be the biggest joke one could possibly say. There's only a handful of store worldwide.
Well I am double checking and I see they have shops in the top 5 cities now. Maybe things have changed for the better. Last time I tried to buy an Apple product there was simply no shop in a hundred miles radius.
