I don't really want to get into a full blown explanation of Pulse Width Modulation but very briefly the granularity of duty cycle (number of speed gradations) is a separate parameter to the modulation frequency.

Increasing the frequency will not give you more control "steps" but it will make the motor run more smoothly and respond to input faster up to a point but the flip side is that you loose power transmission efficiency (generate more heat) as you increase it so its a trade off.
