Best processor (i386) for Python performance?

Python applications are often memory intensive, so a fast bus
and a large cache should help. Also, raw clock speed should help.
Hyperthreading and AMD64 are irrelevant (although for the latter,
it would be interesting to see how linux-x86 compares to
linux-amd64 on the same machine for Python performance).
