Interestingly, the Balanced plan by default keeps my CPU around 45 C at idle. Task Manager reads 4-4.2 GHz, and HWInfo64 reports power consumption being around 60 Watts. Only if I drag the Power Mode slider down to Best Energy Savings do the cores throttle down to 3 GHz when idle, and power consumption gets halved (30 W). Temperatures drop by a good 10 C too.
The Power Saver mode has the best idle results with 2.2 GHz in my testing, but it messes with boost behaviours under load. It would be nice to have a real balance between the two.
1. Temps are normal and have been since last July's launch of 3000. Owners need to stop thinking of CPUs as either being "idle" or "load". Usage is always a constant spectrum, and Ryzen behaviour reflects this. If you've walked away from your PC and it's truly idle, it'll be down in the 30s and low 40s.
2. If you see 60W at "idle" on SMU package power or Core+SoC Power, then you're really not idling, regardless of what plan you're on or if even if you have C-states disabled. Ryzen doesn't work that way. 50-60W and there's most likely an application in the background loading up one or two threads. Again, "idle" is rare in reality.
3. These "3GHz" and "2.2GHz" clocks mean nothing, because outside of a meaningful amount of load, the "Core Clock" reporting for Ryzen is bogus. "Effective Clock" in HWInfo, and Ryzen Master's reporting, gets you much closer to what's actually going on in the cores at idle.
4. If you're interested in more accurate clock reporting, the current version of HWInfo has a "Snapshot CPU Polling" option in its settings. Doesn't affect effective clock, but on Core Clock and Ratio it'll be closer to effective clock and not so much the "magic" rated boost numbers that AMD wants to show you.
