The program that seems that it would be most dependent on
architecture/instruction calls would be Fftw3.  It's not optimized for
i586 or i686, only i386.  AMD K6 and cousins might prefer i586, big boy
Athlon would obviously prefer athlon, Intel would prefer i686, and
pentium4 architecture for P4s.  However, those optimizations have to be
specified during the configure stage before compile-time.  You can't
choose both Intel (SSE) and AMD (3DNow!) optimizations at the same time 
though, can you?
