No it isn't.  In 32 bits mode the processor only has a paltry eight
registers and in addition it is limited to a brain damaged stack model
for floating point.  In 64 bits  it has sixteen registers and possibly,
not sure about it, a healthier floating point model.

So out of curiosity I converted flac to ogg in both modes and it is 30%
faster in 64 bits
