Speaking Intel for a moment, since I don't know all the details for AMD and Apple, their CPUs are nowadays designed to boost until they reach 100C if they weren't already power or frequency limited by then. Intel also provides a 3 year warranty when the CPU is operated to spec, which includes the aforementioned. AMD does likewise, though their CPUs' thermal limit is 95C from what I know; I assume they have a similar warranty period to Intel. Apple also seems fit to operate their CPUs like that. Given all that, I'm going to presume that advances in fabbing tech mean CPUs today tolerate high temperatures better than ones from yesteryear.
