it will depend on what amp you are talking about.
most people consider 驱动能力 to be a power amp's ability to drive low (
resistive) load. for audio amplifiers, that's the ability to drive a 2 ohm
or 4 ohm load, vs. a 8ohm load.
in most cases, it is determined by the output stage's ability to handle
large current. this is typically done with large power transistors, or large
die area for its output stage (paralleling multiple output devices).
sometimes, it is also the ability to drive non-resistive
