Did you done calcs i asked you ?? No. Instead you are comparing aplles to oranges. Laptop chargers have typically way higer Vout than 12V in ATX standard.
So their Iout is way lower at the same Pout levels as for desktop PSU-s.
Why should I? You think I would bait on such childish bait? Unlike you I deal daily with those, especially with failed units from RMA channel. Nor your complaint actually proves something as I said, people do not care about the specifics, they never will. There is a black box that does the power thingy, and leave it there. We are not discussing engineering design choices with economic tradeoff Vs performance gains, and when we can state that the platform is over engineered. The reviewers also must steer away from it, just as making stupid badges.
Most mainstream laptop chargers are type c and are PD capable these days, they support granular voltage steps at very high loads, does output voltage differences make some drastic changes using modern designs? No... You have to thank Qualcomm and other makers investing to quit the shitshow intel does, that's pretty much it.
If you look into high power bricks, like Delta does, they are usually bleeding edge designs unlike PSU's, more space, more budget to cheap out, there are flops, there is no denying about that, but I cannot share the details.
I am completely with Johnny about PSUs being passive, that's masochism, best of any worlds is hybrid, that ramps up still after a time, like 20 minutes to cool heat buildups from caps, not completely passive rule binded by current consumption, that's crazy, I have never understood how the hell it is allowed.
. Look at 3rd one ( anti clockwise counted) - you have way higher reverse current for hot diode. At almost two orders of magnitude higher reverse voltage. Sure - this part of loss is not as high as losses in first quadrant but they are going blatantly in opposite direction. And keep in mind real doiodes have their conductive connectors too. So total loss is a sum of few components. And their ohmic loss increasing for sure along the temperature rise.
