$ time povray --benchmark +WT1
This should max out one core with some intense floating point calculation. But when I check as it runs:
$ sysctl hw.cpufrequency hw.cpufrequency: 3000000000
Why isn't Turbo Boost kicking in? The machine is otherwise idle apart from the Safari window in which I am typing this now, this is the scenario as I understand it that Turbo Boost was designed for?
Just for interest, this machine completes this benchmark in 13m25s and our iMac 3.2Ghz i5 completes in 12m58s - I'm not seeing that paying the premium for i7 was worth it :-(
Update: Well having done some more research, I am getting some boost, according to the Intel Power Gadget:
But I still can't match a 3.2 Ghz i5.
