Depends on what you consider 'smaller'.

a 9mm pistol/submachinegun round has a bigger diameter than an 
assault rifle
round.	(9 millimeters versus 5.56 millimeters.  However the  rifle 
round
has a 'longer' cartridge which allows for more propellant.

Theoretically a smaller diameter round, like a thin flechette will 
penetrate
armor much better.  By that logic, a 5.56 rifle will have penetration
superiority over the 9mm... then you factor in other variables such 
as the
length of the barrel (which determines how long the propellant has to 
work
on the projectile and thus it's muzzle velocity) , the grade of 
propellant,
the materials the round is made out of, etc.
