IActiveView::Refresh invalidates all of the caches.  This is a very inefficient operation; typically data from just one source has to be reread from the database and the rest can be drawn from cache.  IActiveView::PartialRefresh uses it's knowledge of the cache layout to invalidate as little as possible and should be used whenever possible.
