Well, if we're basing the plate armor as similar to medieval metallurgy, then it can't be any more than 6 mm thick. Any more and the metal armor becomes too heavy and cumbersome for the soldier to wear. Now magic will enhance the projectile of a throwing knife or arrow, but that only enhances the kinetic force on impact. It doesn't make the projectile faster or increases its mass. Now if we go back to the standard formula of Kinetic energy of 0.5mass x velocity, the reason why the bullet delivers more kinetic energy despite having less mass is because it's going at a much faster speed.
