I will say not that bad considering lowest clock only down to 3.3GHz in idle. Would be better if can lower to sub 1GHz in idle, for sure that is going to help on idle power.
My swap from Intel to AMD decision happened within 12 hours last week without really keep up with AMD Zen design since 2 years ago, let alone those in depth details. All i known was AMD rule the high end segment now without answer from Intel.
So basically i left no choice when my motherboard dead on me suddenly (I thought is motherboard end up is 1 of 4 RAM stick fault after swapped to AMD, what a costly mistake

).
I try to pickup everything within a week, PBO, curve optimizer, architecture etc. and start to learn there are quite alot of drawbacks of AMD platform as well, both on the processor and chipset as well, especially memory latency side and memory clock limitation wise.
Currently my rig looks stable in everything, all/single core boost is satisfying, except a crappy cold boot issue of my board, and this is a famous issue online for Asus Rog Strix B550-E series with DOCP enable, consequences of not doing enough homework before land for this board.

Zen3 (or any Zen generations) cannot idle at 1ghz. The CPU will simply cease and BSOD. You can further lower clock down state by lowering the minimum CPU state in Windows power plan. But if you ask me, there really isn't that much of difference because the CPU will keep boosting to beyond 4ghz anyway the moment you do something on the desktop, even as much as opening a folder.
As for cold boot issue, you have 2 choices:
1) Flash to an older known working BIOS.
or
2) Tweak the LLC and voltages + RAM timings manually.
Zen 2 and 3 has great so far for me too. The kind of multi core perf that simply can't be had with Intel atm, yeah - few minor irritating issues here and there that plagues some users (touch wood I don't have them) outweighs it. I save time doing work and earn more with it to buy the next best thing, be it Intel or AMD.
