A high(er) end smartphone has a battery capacity of approx. 0.019kWh (5000mAh), a gtx3080 has a max power draw of 320W so running that (at max load) for two hours is 0.64kWh, which is equivalent to fully charging ~34 smartphones.

Thanks for actually doing the math.

So the headline must be false, since you can generate a lot more than 34 generative AI images on a 3080 in 2 hours. That's if you just include inference though.

I wonder if they are somehow trying to factor in the training costs.
