The obvious case is an NLE, when rendering a simple 2mn scene costs half
an hour. Spreading the rendering across processors allows to speed up
things a lot.
Now, if you can't do that, that means you have to cut your scene in
subscenes and render them in parallel, but the cost in memory (and so in
cache misses) seems higher to me.
