I can't think of anything intrinsic to D that would result in any 
difference when compared to similar c++ programs. DMD itself may 
sometimes make some poor decisions from an AMD perspective (as 
Ian mentioned), but if you're looking for every last drop of 
performance you will want to be using ldc or gdc anyway.
