Bullet Diameter Vs Knockdown power

Ok, just an academic debate here. But what effect does bullet diameter have on knockdown power, all other factors being equal.

Lets say a 7mm bullet of 165gr moving 2400fps and a .30 (or 7.62mm) bullet of 165gr moving at 2400fps.

Now equal weight and equal velocity = the same energy delivered on target IF the bullet comes to a stop within the target.
But will the larger diameter bullet transfer the energy faster resulting in a significantly more "shocking" impact?
And if the bullets both exit out the other side of the deer, will the larger diameter bullet transfer significantly more energy to the target on its way through.

I guess my mind is made up that the 7.62 or 30 cal round WILL "hit harder" the question is, (if I'm right, lol) will the difference be significant or immeseasureably small.
