What I want to know is whether on-board sound uses any more processor time
than a dedicated soundcard using the same sound chip.

ss.

Yes it does. Use a seperate sound card

No, but why would you want a sound card with the same chip?

The same chip will have exact same CPU utilization on a
card, and when it's on the motherboard (unlike southbridge
integrated sound support) it's even on the PCI bus just like
the card would be.

Primarily the card "might" give you better analog filtering
because it has more room for the filter circuitry. That's
always true though, some cards are very cheap and
minimalistic compared to other cards.

I would have thought sound support integrated into the southbridge still
appears like a device on the PCI bus. How else would it work?

The PCI bus on a (southbridge-equipped) chipset merely
connected the PCI devices TO the southbridge. The
southbridge can (and does now) have integral features that
have no need to connect to an external (PCI) bus but rather
more directly connect to the northbridge.

PCI bus connects two (or more) chips. If sound is integral
to the southbridge, what on the PCI bus would it then need
to connect to? The digitized audio leaves the southbridge
on separate traces to go to the codec, it is a serial bus
with no other functionality nor data bandwidth issues to
resolve.
