Why does the same graphics card made by different manufactures have different power consumption?

I'm talking about Sapphire rx480 8gb nitro+ OC and MSI rx480 x 8GB. Sapphire one has power consumption of 225W and the msi one has 150W even though the msi one has higher clock speed.

as you see, those are opinions

the recomended psu remains the same for the reason i explained, a 75 watts extra connector will not be used fully, perhaps only 15 or 20 watts more, so the psu will remain recomended as 500 watts, because gpu + cpu and other parts will not use over 400 watts under load so there is space to add more devices or space for overcloking, as i mentioned overprovisioning

one manufacturer believes that 150 will be enough

the other thinks that overclocking it might reach over 150 watts so he adds another 75 watts connector

each board has different design and components, so results are different, sometimes not by much but manufacturers must over-provision their cards to avoid bad surprises

Yeah but the overclocked one requires less and even the more confusing part is that they both have a recommended psu of 500W so what the hell
