Imho they can as long as they agree to drop some sort if retro-compatibility.
Modern cpus being able to run dos software is certainly nice, but it’s probably preventing intel/amd from performing some aggressive restyling and optimisation/refactoring to their isa and its implementation in silicon.
Apple on the other hand happily deprecates its own os releases and the hardware supported. Software retro-compatibility is then achieved in software (rosetta and such)

- saagarjha 4y agoI've heard numbers like 5-10%.

Most of the legacy instructions are implemented via microcode anyways, so the amount of resources dedicated to legacy support is minimal.
