I can't give a specific answer. However, I will point out that in
addition to the performance gain from a simple implementation of the
code in assembler, and a processor-specific hand-optimization, to
leverage the features against its weaknesses, etc., the 64-bit
processors have an additional advantage.

I'm not doing the code, so I can't tell you for sure, but everyone
working on it is aware of the Biham-type optimizations for 64-bit
processors, which should provide still more performance. They should
kick butt.
