If the question u are asking is whether the processor being 64-bit will benefit its capability of running 32-bit applications, then the answer is no - except in some very few outlier cases. There are reasons why AMD processors are better for gaming.. And it being 64-bit is not one of them. Similarly, an AMD chip being the "color black" or came in a pretty box has nothing to do with its superior performance in 32-bit applications either. I would imagine, everything being equal, if AMD came with a 32-bit processor, it would probably be "faster" in 32-bit apps than the 64-bit processor, since resources aren't wasted - like the cache.
