Ryzen Balanced Power Plan. 90-100% frequency. How much power is being used?

[sn2x]

I've looked for results of power consumption compared with balanced, power saver and AMD Ryzen balanced(90-100%) but couldn't find the numbers.

All I know is that with the Ryzen Balanced Power Plan that frequency stays at 90-100% with the voltage always nearly maxed out.

Is the extra power used something I should be concerned about with either a first or second generation Ryzen CPU?

Sorry, I can't measure power consumption. But according to AMD, the CPU will idle regardless of what Windows shows, even on the high performance power plan.

You can lower the minimum processor state a lot more than 90%, I use 20% on my first gen ryzen. If you have manually overclocked then you need to set up p-states in the bios for it to drop the frequency, mine is set to drop to 1ghz 0.85v at idle, but if you're leaving it on default settings it should manage itself just fine. And don't worry about setting a low minimum percentage hurting performance, I've found it doesn't take a lot of load for it to jump up and hold at higher frequencies, games are more than enough to keep it at full clocks so I don't even bother changing to the high performance plan most of the time.

I don't know about power consumption at idle, if you're concerned you could get a wattmeter socket and see for yourself. It won't be a lot though, even in the high performance plan.

edit - just had a look in hwinfo. With ryzen power plan, 20% min state, idling at 1ghz 0.85v the SoC + Core was 13.5W, when in high performance plan at 4.15ghz 1.45v (pretty much worst case!) it was reading 35W. So there's a bit of a saving there I guess. For me it's less about saving energy and more about prolonging the life of the processor while heavily oc'd.

My motherboard has one of those useless RGB stripes running over the sound card, I have it set to show CPU temperature, so it gets red over 60°C, blue between 40 and 60, and green under 40. It only reaches green when the CPU is idle, and i can tell you that even with both limits at 100%, or with the low limit at 0%, I get the green LEDs. Maybe it takes a little longer at 90 or 100%.

Thanks, just downloaded hwinfo to check my consumption numbers. Not able to change p-states on my board, but I did lower the AMD plan from 90% down to 20%. That saved about 4 watts for me from ~29w idle down to ~25. Compared to ~13 watts from the power saver plan(which reduces performance) I suppose I shouldn't be concerned with an extra 12 watts.
