Yes. On my Athlon-64 2200+ system on my desk, the 'opteron' version 
encodes a 6722 block sample file in 478ms; the 'i686' version does it in 
514ms. The 'i386' version is somewhere near 600ms, since it has no fancy 
instruction scheduling.

Interestingly, _all_ of the 32-bit x86 optimized versions run just fine 
on that machine, meaning that GCC did not opt to use any instructions 
that are specific to a processor model/family... the performance 
improvements come only from scheduling the instruction flow.
