The point they can’t process as many instructions per clock cycle and there’s nothing they can do about it. They can’t match the M1’s performance per watt.
And certainly there’s no Intel/AMD laptop processor with 8 or 16 Gb of RAM via a 128-bit memory bus on the same die. Same thing with a 16-core Neural Engine with an OS with the APIs to take advantage of them.
Regardless, the big win was giving unified access to that memory using a memory fabric. That lets the GPU (for instance) access graphics assets with no copying - it just uses them in place.
AMD can absolutely do the same thing, if it desires. Intel can too, but it has a hill to climb WRT GPU performance.
Apple's AI chiplet is another matter...
