I've just tested letting a Youtube video play on my M2 Macbook Air.
At 25% screen brightness, it uses around 4 Watt.
At 50%, around 6 Watt.
At 100%, around 11 Watt.
The person in question is unlikely to have a modern computer, but letting a video play all the time could technically still be using less power than the light.
- gibspaulding 3y agoThat's insane to think about. Extrapolating down to 0% brightness means the actual compute required to manage the network connection and decrypt and render the video, plus anything the OS is doing in the background happens in maybe 2 watts?! With 2 watts you could power a fairly dim LED lightbulb or perform the equivalent of thousands(?) of man hours of hand computations. https://xkcd.com/676/ https://xkcd.com/676/
- trvz 3y agoThe computer idles at 3.5 Watt. A 1440p video is played at 4.0-4.5 Watt at 0% internal screen brightness. The same video at 4k uses 4.5-5.0 Watt. And at 8k, it's 15-17 Watt. The xkcd is apt, as usual. The last time I felt with Intel as I feel with Apple since the M1 was with Haswell.
