To be relevant, such data gathering should be performed on non-x86_64 
capable CPUs, because there are already fully optimized Fedora packages 
for x86_64.

So that's Pentium 4, Pentium M or their Celeron or Xeon versions, Atom 
or VIA C7. There does not seem to be any AMD CPUs that supports SSE2 but 
does not support x86_64.
