G73: Prime95 Bench [Turbo On/Off]

I thought I'd run Prime95 through its benchmark with Turbo On and Off.

Turbo is definitely not an improvement, as others have also noted.

 

Yep there's something interesting going on with these CPUs that's for sure.

Some benchmarks do run faster (Cinebench, 7zip) and almost every game I've tested does as well (using an INGAME measurement not a benchmark or playback). When I was playing with OCing properly on my i7 quad, I noticed quite a few times that of 133 (stock), 140 ("Extreme Turbo") and 148 BCLK, the Extreme Turbo was the slowest of the 3 and the >10% overclock did actually show roughly 10% increased performance.

I suspect it is to do with Turboboost's reduced frequency step-ups with increased power consumption but because that happens a zillion times a second there's no way that I know of to accurately measure using 3rd party monitoring software other than an "average multipler" in something like i7turbo but the differences are so small it's nigh on impossible proving it's not just margin of error.

 

I can easily OC the i7-820qm to 2.53ghz with SetFsb and that does improve preformance pretty well.
Before i formated from stock install, i tried out the Asus turbo button and it also did nothing for me, the performance was actually worse with it on. Its there just for advertising it seams.
