This can be effective on motors where the vehicle comes with both I4 and v6's and bigger as they tend not to put in a smaller radiator for a smaller motor it is easier just to keep the same parts in them.
This has nothing to do with efficiency. You're talking about cooling capacity or capability.

In heat transfer, higher efficiencies are attained by a higher heat difference in the medium and transfer fluids.
