[Superman] Is Superman’s superbreath an extent of his super strength or is it an independent power

What I mean is that Superman is better at everything than a normal human. I know Superman’s ICE BREATH is an actual superpower, but what about his superbreath? 

For instance, I’m much stronger than an ant so if I blew on it, the ant would fly away. If I blew on a person, it would be unaffected. If Superman used his superbreath on an actual kryptonian would it be the same as a human blowing on another human, or would it feel to the kryptonian like they just got punched in the face.

Another way to phrase this would be “Is Superman’s breath proportional in his strength to a normal human, or disproportionately stronger”

Super breath is almost certainly a separate power since if he just blew hard the volume of air he could blow out is limited by the size of his lungs and the effects we see from super breath couldn't be achieved with just 6 litres of very high speed air.  So either Superman has some sort of pressure vessel in his chest and he's constaintly compressing air when no one notices,  he has some sort of additional air intake that connects to his lungs or the air comes from the same place the Hulks extra mass comes from.
