Yes, to clarify above: The expected result on pre-965 is just that it
will change performance for different workloads, some for better, some
for worse. It's not like on 965 where we've got changes that are
speeding up everything you do with Render. I can imagine both large
improvements for the "better" case and large losses for the "worse"
