Laptops use 5W (Mac) to 20W (Lenovo Yoga with discrete Nvidia)
Steam box uses 400W under full load, 70W idle (Ryzen, 4070Ti) but these are rare and off most of the time.
They may be more that DC machines.
But most people run on battery and no fans, that gives them 1W power budget sustained, and a TDP of 5W.
It is useful to design for long battery runtime but it has no ecological impact.
