True idle being better would be nice but if I want true idle my machine is powered off... so my typical usage looks more like this versus having the flagship CPU from the competitor:
I think if Your PC is not idling most of the time, it means it is either for gaming ( in that case the flagship from other vendor is okay in power use ) or is running some sort of throughput load non stop ( in this case You've bought wrong CPU, as 7950x would work better in peak perf and perf/watt).
The reality is that for most of the users PCs are idling most of the time or the load is very light ( like watching some video ).
What is completely wrong tho is incompetent AMD engineers and their buggy chips. There is no reason for package C6 to be bugged and there is no excuse for idle power consumption to increase with each newer AGESA. They were forced to disable some DF power states, is what i've heard online. That means ~ +5W at idle going from 1.04 to 1.05 AGESA on this system. Quite an impact when whole 12/13th gen Intel's chip idles for less.
Sure their intentions might be good - working around some bugs in silicon by disabling power states, but that does not make them less incompetent.
