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.
@killyourfm Thats a lot! My 2018 MacBook under full load uses the same amount of power like your idle system.
And to clarify does this include the screen(s) and peripherals or just compute?
@vsaw This is JUST the PC! (I can only measure one input on the Kill-a-Watt)
@killyourfm If you are interested in measuring your entire setup, You could get an extension cord plug all devices in and measure all of them at once with the Kill-a-watt.
@vsaw Huh. that's a fairly simple solution I hadn't thought about!
My guess is though, the screens won’t make a big difference probably 20-50W. At least my “old” 1080p screen was using this much.
@vsaw True, true. And what I'm really trying to capture is the power consumption differences between operating systems, form factors, and eventually proprietary vs open-source software.
@killyourfm Oh there is loads of fun to be had with this. A while back I found a research group looking into energy consumption of video streaming on Android. TLDR, 720p cuts it down in half compared to 1080p https://s2group.cs.vu.nl/2022-01-05-green-lab-experiment/
@killyourfm Here are some people and organizations you could check out if you want to learn more about energy efficient software
the software and sustainability research group https://s2group.cs.vu.nl/
https://www.thegreenwebfoundation.org/ which build the awesome CO2.js library
@fershad who works for the green web foundation and has a CO2 aware homepage
https://www.blauer-engel.de/en/productworld/resources-and-energy-efficient-software-products a German certificate. Super cool fact: the first software to get the certificate is #KDE #Okular
Oregon Coast Trail @killyourfm@layer8.space@vsaw @fershad
Some context around that super cool fact: I watched Joseph's presentation (from KDE) at LAS last weekend about their Blue Angel certification and software sustainability -- that is precisely what inspired me to start this testing!
(I'll also be seeking the same certification for Thunderbird)
