I have the same P4 vs. Athlon question as many others, but have a specific application whose performance I must optimize. I run lots of scientific analysis code that I write in (god help me) Fortran. Nothing too memory intensive, just lots and lots of simple floating point arithmetic. At present I run these on a P3 500M with execution times running up to 10s of minutes (and many runs required for a final result).
I see that Intel has just brought out a new Fortran compiler that supposedly generates code optimized for the P4. Assuming I recompile all my code with this new compiler would the resulting runtimes be fastest on a 1.5G P4, or would I do better just using my already compiled code on a 1.2G Athlon?
Any advice would be appreciated.
Thanks,
