impact wrench torque rating

I'm shopping around for a new 1/2" impact wrench.

I noticed the cheaper ones have a lower torque rating than the more expensive ones. However, for the most part each has the same air requirements (pressure and CFM).

So if the air requirements are the same how does the more expensive impact wrench output more torque?

Is there something mechanically different inside the wrench?
