Memory Write Invalidate performance gains?

[Neal Palmer <neal@dinigroup.com>]

I am trying to figure out if there is any system performance difference in
either bridges or target devices when the master initiates a Memory Write
and Invalidate rather than a Memory Write.

Does anybody know of a list of devices that behave differently with the
two commands, or at least a list of different functionality that
specific classes of devices will do when given the two different commands?
