Over the next few weeks, I'm going to TRY to accurately measure my power consumption doing daily work tasks on my big tower PC, the Steam Deck, and the HP Dev One laptop. (Using a Kill-A-Watt P3).
ALSO? Gaming power consumption comparisons between my desktop PC & the Xbox Series X, both at 4K resolution.
I expect it will be an eye-opening experience and I'll never turn on my tower again.
This will undoubtedly branch off into all kinds of software testing too. YES, I'll record & share data...
I ran some power consumption tests on #Windows 11, measuring from the wall.
My system: Ryzen 9 3900X, Radeon RX 6800 XT, 32GB RAM.
1% CPU utilization (Idle): 67W
5% CPU + 10% GPU (Streaming with Plex): 130W
Dirt 5 Benchmark (4K, High Preset, Uncapped FPS): 431W
Dirt 5 Benchmark (4K, High Preset, 60FPS Cap): 355W
Dirt 5 Benchmark (1440p, High Preset, 60FPS) Cap) : 288W
The power savings gained JUST from capping FPS to 60 is more than 2x the total power of a #SteamDeck under heavy load.
Starting #Fedora 38 power consumption tests, and decided to see how much extra power gets consumed by simply switching refresh rate from 60Hz to 120Hz (as this demands more work from the #Radeon card).
[As a refresher, it's a tower PC w/ #AMD Ryzen 3900X + Radeon RX 6800 XT]
- 1% CPU utilization (idle) @ 60Hz: 67W (this is the same result as Windows 11, btw)
- 1% CPU utlilization (idle)@ 120Hz: 97W
So an extra 30W pulled from the wall just to double my desktop refresh rate. Is it worth it?
In the UK, at 8 hours of operation per day, that 120Hz refresh rate boost would only result in about £30 per year.
But that ecological footprint multiplied by millions of people? Well, that might truly suck. Especially when we add up all the other "quality of life" things we enjoy with modern desktop PCs.
(I don't know how to make these calculations, and maybe this is something that @be4foss or @baldpolnareffart would excel at?)
@killyourfm I love what you're trying to do!
How are you collecting the data? Keep in touch, I'm interested at doing something with it
@baldpolnareffart Right now I'm just throwing notes and results in Joplin. Not very organized yet. But I would like to make all this public, and have other people running similar tests.
@killyourfm I think before collecting data from various different people, we should try to organise some sort of guideline to follow, just to make sure everyone who's involved is on the same page.
We could start collecting individual data and try to look for interesting patterns before asking the community to submit anything
@baldpolnareffart I'd prefer looking to your for guidance on methodology. Let's take this to email!
An established methodology is one of the benefits of the Blue Angel ecolabel award criteria. We document the process in the KDE Eco handbook:
See these publications for information about the methodology.
"Sustainable software products -- Towards assessment criteria for resource and energy efficiency" (Sec 4.1)

And this German Environmental Agency report, pp. 22-27 summary in English:

@be4foss @killyourfm That was gold, thank you!
@baldpolnareffart @be4foss Indeed, that handbook is a great resource.
And I think the Expert Power Control 1202 might be JUST A BIT more useful than my Kill-A-Watt :D
