The 1500x has a 65w TDP, as does the 7500. They both use the same amount of power.
I know that they have the same TDP.
Nvidia optimus balanced usage of integrated graphics and dedicated graphics so it uses less power.
What im asking is what abt the amd ones, bc they dont have an integrated graphics with it, so im guessing that the dedicated graphics will always be used right, so i uses more power, isnt it?
