Just to avoid the confusion, are you saying that 64-bit capable processors are faster than 32-bit only or that application compiled for 64-bit architecture is faster then the same application compiled under 32-bit architecture on the same hardware. The reply to your post tells me that people think you mean the former, where I was talking about the latter. I will not dispute the claim that 64-bit CPUs are faster then 32-bit, cause I don't think they make 32-bit only CPUs anymore (at least in the x86 architecture). So any 32-bit CPU will be just plain outdated and therefore slower then any modern 64-bit (and 32-bit capable) CPU. As for the applications, I believe the difference should be negligible unless the application is trying to use a lot of RAM. I think I have seen some benchmarks confirming this, but at the moment I cannot seem to find them.
