Yes- maybe it is, because sometimes at 105% it doesn't throttle. It is a matter of a certain spot in benchmark.
Anyway - In Far Cry 3 at 4xAA, 1080p, everything on Ultra and view range maxed out I get 100% power usage but it NEVER clocks down from my 1333 MHz on core.
That way I am getting 45 FPS stable which is great outcome, considering the fact, that in reviews this card got 45 but with AA turned off.
I love this gpu!
And my temps never pass 55 degrees.
So my final settings in afterburner are:
+114% power target
+110 Core (but here it depends on what Your boost is so don't set it straight away)
Which gives me:
Core with kepler boost: 1333 MHz
Memory effective: 7400 MHz
177.8 GB/s (!!! - almost as good as gtx 670 although it has wider mem bandwidth)
So these performance values in GTX 680 STOCK looks like that:
Basically I gave myself GTX 680 performance (need some more memory tweaking) but saved up loads of $.
I am happy indeed
One more interesting thing about throttling - it happens only in 3dmark11. I tried 6 different heavy GPU games - card never throttles even at 100-105%. Guess it's 3dmark mess up. But I don't play benchmarks, I play games so I don't care
Also I tried OCing my core to the max:
At +100MV I got myself almost 1400 MHz Kepler Boost clock. But I'm affraid of running on such high overvoltage.Edited by Mephic - 3/20/13 at 2:52am
