How does that make the chest stronger.
For one thing, you're lifting your entire bodyweight with dips, whereas with push-ups your legs are being supported by the ground.
You are working far more muscle groups than simple pushups work, not to mention the added weight as the others have pointed out. Also, pushups are known to be the cause of wrist injuries.
Taking the actual weight lifted out of the equation (which, of course, dips wins by default), the actual angle is better at developing triceps and the stretch component (which itself better predicts how much that exercise can stimulate real growth) upon both lower and upper pecs is better. Finally, because the body moves with less restriction through space, your grip has to be firmer for the dip. That in turn increases the neural drive -- again all other variables being equal -- which translates to more active motor unit pooling and thus real-world strength gains.
