For example, on Pentium 4 you have to recompile and target SSE2 instructions if
you want to get good floating point performance.  If you don't recompile with a
optimized compiler that supports the P4 specific instructions you often times
don't get as much performance as you would expect.  The same is not true for
Athlon or Opteron which will simply run good old Pentium III code faster.
