Around x64 cpus you have plenty of peripherals that are subtly different too. Arguably the situation is "worse" for ARM, but it is getting worse every year on the x64 front too, esp since MS decided to release extremely short lived OSes quite fast, without really any fixed HW support policies. In the end I've recently had built-in ethernet on a recent Intel not recognized by a few years old Linux distro, so at the end of the day it does not matter much if you can't use a computer because of an essential "peripheral" or because of an interrupt controller; and if you have recent enough software it will be supported in both cases.
