This is outdated in a big way with stable diffusion turbo and the recent LCM models that can render images at 30fps on a 3090.

360w * 1s /60 seconds a minute / 60 minutes an hour = .1 wh/image

30 images a second? .033 wh

A phone battery is 3000 mah * 3.5volts = 10.5 wh

318 images per phone charge

My math is probably off, but you get the idea.

You're off by 3 orders of magnitude. 30 * 0.1Wh = 3Wh

That's ( fixed, messed up mah conversion) .1wh for a second of 3090 time/ 30 images a second.

If a 3090 drew 3 watt hours in 1/30th of a second it would melt.

Possibly off by one order of magnitude though... Editing post to see, and it looks like I was. 300 images per charge instead of 3000.
