What workloads?  Are you comparing using the same hardware?  To me, the 
advantage of 64-bit is when you have more then 4G ram or are working 
with very large ( > 4G ) files.  It is also useful if you are doing 
extensive numerical calculations that need high accuracy.

In most cases a 64-bit executable or library is about 20% larger than a 
32-bit executable and takes longer to load and uses more ram, but at the 
speed and size of most systems today, this may be negligible.

Human interface research has shown that applications like the desktop 
need somewhat more than a 20% increase to be noticeable.  For instance, 
I really can't tell the difference in interface speed between my main 
system, 3.2 GHz system, and my wife's 1.8 GHz system.  I do notice the 
difference when doing compiles though.
