Is there an efficiency difference between these two implementations? And if there is, any explanation, clarification and depth you can provide would be apprecated.

Code:

min(A, B) when A < B ->
  A;
min(_, B) ->
  B.


min(A, B) ->
  if
    A < B -> A;
    true -> B
  end.

I've done some measurements under R13B03 and it seems equal. It's probably compiled to the same bytecode.
