Matlab
Matlab N72

Matlab is a single threaded application and so it does not take advantage of the second CPU. Nonethless, here we see the advantage of the 128-bit memory architecture of the Opteron over the Athlon64. Matlab users have historically preferred AMD processors, and the Opteron and Athlon64 should continue this tradition.
Preliminary Conclusion
It seems like the Pentium 4 and Athlon 64 3200+ are very closely matched for RAW processing and the Fred Miranda scripts. However, the Athlon64 takes a considerable lead with Neat Image, the most CPU intensive application in our digital photography test suite. Equally important is the fact that NeatImage has become one of the "must have" applications for any digital photographer, amateur or professional.
