AFAICT, Apple has three major advantages (note that architecture only has minor impact [1])
- first access to the best process
- a great team
- high bandwidth / latency DRAM
Intel & AMD aren't that far behind on #1 and #2, but I'm surprised at how long it's taking them to catch up on #3. If they created and sold a chip with wide low latency DRAM on package they would simultaneously significantly increase their performance and also they would capture a higher proportion of the BOM cost of a laptop.
Pedantic: AMD's MI300X has on package RAM, but it's not exactly a laptop chip...
