x86 is quite a bit older instruction set. It has a lot of cruft and the all chips are really backward compatible with older software and many operating systems. Its extremely flexible at a cost to performance. The new Apple chips while impressive, only run new ARM64 instruction set programs compiled for apple machines. Depending on your use case that might not matter, but its still something. And competition is good for a cpu market that was lacking the massive year to year improvements of 20 years ago..
