Apple didn't convince anyone of anything. The only reason that the M series chips are good is because they are ludicrously expensive to produce, and a massive die. It's not because they broke some boundary.

The M1 Max is the size of an AMD 5950X, and a 30 series GPU PUT TOGETHER. It's not some Apple magic sauce. It is on the most advanced node you can get manufacturing wise, it is incredibly large, which means it is ludicrously expensive to make. The only reason it works is because it's in an Apple device that is integrated top to bottom. It would never work for an off-the-shelf component. And it would also never work in a cheap device.

Don't get me wrong, it's a very well performing, very efficient chip. But it's that way because it's incredibly expensive to make, more so than any dedicated desktop CPU on the market right now, with the most advanced manufacturing.

To top it all off, there's no reason that a chip like this could not be socketed. It could easily be designed that way. If they wanted to, which they obviously do not.
