Some cameras have dedicated processors just for AF which I imagine will speed it up even more.

The dedicated processors may speed up AF a tad, but the real reason for that feature is for better tracking in AI Servo.  There the processor tries to calculate where the subject is heading and thus anticipates the focus distance.  This is a feature addressing the needs of the professional sports shooter.
