what is more efficient?

[charlize]

the "amd ryzen high performance" power plan or the windows "high performance" power plan?

I have been using the Ryzen Balanced power plan myself, was good on my older 2600x and now still using it on my 5700x.

unless amd updated their statement they said to not use the power plans for the 5000 series and instead stick with windows balanced plan

I don't see how the power plan would make a difference. If you really REALLY want efficiency, this is not the way. The only adjustment it makes is that your CPU, which should be a 3000 and probably older series, will run at lower idle voltages because there is always a process that will pop up and cause core(s) to increase to a higher frequency as well as the voltage. The Windows boost algorithm is a bit too aggressive for them.

I don't go by MS plans, always custom, for a gamer system, keep sleep/shutdown timers off.
But then you have to turn all the green stuff OFF in Bios also.

It should make virtually no difference unless you are having issues with hardware that cannot use C-states and P-states or you use a power supply that has a driver and interacts with Windows and it is possible for it to be set to ECO or low power mode or dynamic power mode

Fairly uncommon issues to have outside of laptops, where some brands enforce low power on their cheaper hardware or issues with some graphics cards that may not have full support on the platform you are using.

One other area is compute, but no one serious uses Windows anyway. Certainly not a retail version.

In those cases high performance might give a better experience. Might because hardware can ultimately override whatever you are trying to do in software and since there are so many combinations in hardware and software, you cannot know until you test it.
