And the obligatory profile.. (promise, this is the last one I'll send before someone comments on the others. It is 3:50AM here!) I'm not sure quite how repeatable the profiles are, but this is the same frame (in a displaylist), with same test conditions. (CPU forced to top speed and out of C-states with two busy-loop programs to keep the cores busy). The profile does look somewhat different.
