[rc5] Identical results, two CPUs

The Cyrix Development team decided to go with integer performance.  THat
is why the Cyrix chips are faster than the Intel chips at performing
iteger math like rc5.  Intel chips, however, have better FPU performance,
since they can perform more than one FPU instruction at a time(putting a
command in while one is still being processed).  THere is a great deal of
information about the differences between the two at
http://www.alternativecpu.com.  It is mainly Cyrix orientated, but it
helps to dispel rumors, etc.  If you own a cyrix chip, you may want to go
here to see if you can get a few more k/sec out of your cheap chip.  BTW,
it explains the price diff too.
