One of the groups at work tested an app (serverside java) and they ended up 
with the following results:

Xeon 32bit - 100%
Opteron 32bit - 86%
Xeon 64bit - 97%
Opteron 64bit - 92%

It was a pretty unbalanced test since we ran a 3.6Ghz Xeon against a much 
lower speed Opteron (244 I think but I can't verify that until I get to work 
today) hence the Opteron was quite a bit slower. 
Anyway, the interesting part was that with the 32 -> 64 bit JDK change boosted 
performance about 6% on the Opteron while the Xeon actually lost 3%...
