  The AMD64 processor has additional features (eg. additional registers)
only available in 64-bit mode which the compiler can use to generate
faster code than when compiling to 32 bits. Thus it is expected that
the 64-bit version will run faster in an AMD64 than the 32-bit version
(how much faster depends on the compiler used).
  If you have an AMD64, it just doesn't make sense to use the 32-bit
version of POV-Ray because the 64-bit version should be faster.

  (And by the way, the 64-bit version being faster does not mean that
64-bitness in itself brings magically some speed benefit. The speedup
is not related to the 64-bitness of the processor, but to the fact that
in 64-bit mode it has additional features not available in 32-bit mode.)
