The ryzen 1700 is also from 2017. Intel’s cpus still dominated at the time for anything single-threaded, they were just bad at multithreaded workloads. I’m not saying i/o die power consumption isn’t higher, it is for sure. And I agree, it doesn’t go down at idle because it can’t turn off or do power gating.
What I’m saying is that a computer with a cpu that is 65W TDP (from a time when amd’s TDP was close to being accurate as ~ max power consumption under load), the i/o die (which is part of that 65w TDP; which is for load) cannot possibly be the main reason his computer is idling at 80W. Especially when I linked an instance of a system also with a ryzen 1700 that was idling for 57W and with a similar configuration as an intel contemporary only being 7W greater at idle.
