On the latest Ryzen models, the idle power draw has reached an acceptable range, at least how I have defined it for for myself, considering the advantages the platform does have like the mentioned not-disabled ECC functionality.
For my system, Idle is around 21-23W, Team blue is estimated to be 7-8W lower, at maximum. Not mentioning the initial costs would have been higher or availability not given on time of procurement.
Room for improvement, sure. But tbh, im curious what yet coming kernel updates will achieve here
