Looks like the L3 cache is more like the buffer in a network switch. It
will keep data localized as much as possible to prevent too much cache
coherency traffic from going out unnecessarily.

What I read elsewhere is that only the multiprocessor versions of
the 4-core chips will have the L3. Ie., 4c chips for 1P systems
will not have the L3.
 
Yeah, that would make sense to me. 1-socket/4-core systems wouldn't
have much external cache coherency traffic to worry about.
