It’s all power supply efficiency. More efficient AC to DC and DC to DC.The 1X isn't going to produce consistent results due to variance because of the method of construction. (Hovis method)
If you want fair comparisons you will need to find many sites or someone testing many different 1X boxes.
If the ps4pro is using as much power as 1X, the question I'd have is why? Aren't they on the same process?
