From the root q-d-r which has the following classical Arabic connotations:
to measure something
to make manifest the measure of something
to distribute or apportion (as though by measure), measure-out
to decree, to ordain, to decide a matter (as though measuring it to fit)

Muqtadir is an intensive form of the root q-d-r which emphasizes the Supreme Power to enforce or enact whatever Divine wisdom decides; being omnipotent, having the ability to do everything.
Qādir is a less intensive form of the root q-d-r which describes the attribute of being able to decree, ordain, appoint, measure-out, decide.
These both involve power in the sense of power being the intention by which something comes into being according to a certain measure and a certain willful decree, as in saying ‘kun’ (Be!), and it is.
