At various times in their history where AMD was behind in core design, manufacturing, or both, they cranked power (and thus heat) up to fairly obscene levels to attempt to compete with Intel. That's not the case now with Zen and TSMC 7nm - you cant really compare an AMD CPU now to one even 5 years old, much less 20 years old.
