FWIW, I wrote a fairly early review (in 2004!) of the AMD64 architecture under
Linux, with benchmarks:
I didn't include any video transcoding tests, but using oggenc to encode audio
took 70% of the time to run on 64-bit as on 32-bit.
Of course, modern computers and software are substantially different from
those of five years ago, but the x86 vs. x86-64 (aka AMD64) architectures are
fundamentally the same.
