For both the 1700 and 5800X, the i/o die uses ~12W at idle, and 20W max at load (assuming he’a doing something that keeps the i/o die at max power consumption when everything else is idle). This leaves us with 60W-68W unaccounted for at idle. Even in the worst case for i/o power usage that’s 75% unaccounted for. I keep talking about TDP and load power because even in the case where the cpu isn’t using lower power states correctly for whatever reason, the i/o die cannot possibly be majority of the 80W power usage.
