Does it make a difference that is significant?
I have used mplayer on a 32bit system for many years together with
vdpau. As vdpau does take nearly no CPU time, there was always lots of
CPU available for audio decoding. It may be different if you do not have
hardware video decoding, but sometime we have to decide if the work to
support old hardware is worth the extra mess in the code.
There are a lot of ancient drivers that would be nice to get rid of.
