  Except that the x86-64 architecture has more processor registers than
the x86-32 architecture, which means that 64-bit executables can be
optimized by the compiler better than 32-bit ones. This can cause a
measurable difference in speed.

  (OTOH 64-bit programs will inherently consume more memory than 32-bit
ones, which may also affect speed the other way around. Which one is more
significant with POV-Ray, hard to say. I'd say the registers probably win,
though.)
