If you compare Geekbench scores[1][2] and top 500 "green" supercomputer rankings (gigaflops per watt)[3], you see x86-64 still reigns supreme not only at peak performance but also real world scientific performance per watt:

Apple's laptops nowadays essentially amount to ultra premium Chromebooks. Nice rigs for running a web browser and doing npm+JS dev. Everyone doing serious AI and science is on AMD64 though, particularly AMD64+nVidia, running either Linux or Windows+WSL. The cheapest Apple you can buy with 64GB is $2399 (Mac Studio). Go to pcpartpicker.com and you can build a nice 64GB rig for under $1000 and get minimum 3 to 5 year warranties on all the individually user replaceable components you buy. But if you buy a Mercedes for 2.5x the price of an equivalently comfortable Toyota you get to flex that three pointed star badge on the front of your car....
No offense, but you don’t have a clue about what you’re talking about. Apple’s secret to survival after Jobs returned has always been maximizing economies of scale. Although Mac had no market share in 2000, the iMac was the biggest shipping SKU by far. Because of the education market, the iMac was also the largest selling SKU in the distributor channel.
Even today, Apple sells like a dozen major SKUs per product line, and many use the same components. Dell probably sells 200 laptop models.
The Apple strategy as applied to the M1/M2/etc is super successful. They are selling laptops at a 10% premium that are superior, with 45% margins But… the things that make it the best laptop on the market make it a mediocre high end device. That M1 64GB part is expensive because it’s a low volume SoC.
Macs are about as upgradable as comparable laptops from Dell, HP, Lenovo and Microsoft and all ultrabooks command a hefty premium these days, Apple-made or not.
What's the barrier to competition? You not having money?
