Still not really an apples-to-apples review. GPU Boost dynamically adjusts voltage and the reviewer was unwilling to adjust the voltage on the 7970 overclock. They mentioned not wanting to adjust the voltage and fan profile on the 680, but that tells me they don't really understand how GPU Boost works. You can see on the precision X GUI the voltage scales up with clockspeed.

Anyway the point is both can be OC'd to similar clocks and at similar clocks the performance is pretty much the same.

"Fortunately, GPU Boost goes hand in hand with overclocking and delivers additional frequency in addition to the clocks set by the end user. GPU Boost continues to work while overclocking to the maximum allowed by the ever-changing power envelope."

Glad to hear. Overclocking (not GPU Boost, just the general OC) shouldn't be held back by any power caps, just the voltage limit then right?

Wow, did you really only see one side to that comment?

The 680's that the reviewers have will have been hand picked. That means that the OCs they get may or may not be representative of the average card. Meaning that there is a chance that all the "normal" cards wont even be able to OC much past stock, or that they will be able to match what the reviewers are getting.

So your cotinuous comments about the 7970 not OC'ing as well as in the cards in the reviews can just as easily be applied to the 680s.

Fact of the matter is that with this GPU generation AMD/ATI is closer then ever to Nvidias high end. The gap between the 7970/680 is closer then the gap between the 6970/580. Next Winter will be interesting.

I don't quite understand how you're doing your math...

The chart shows the HD7970 performing at 94% relative to the GTX 680 at 100%. We can then set up a simple algebraic equation with a scalar factor x.

0.94•x = 1.00,
where is x the factor you would need to scale the performance of the HD7970 by to get the performance of a GTX 680.

Solving for x gives us that the GTX680 is ~6.38% faster than the HD7970, unless I'm missing something.

Please go troll elsewhere! AMD is gettin there butt handed to them relax take a pill and enjoy your self. And its pretty much a givn by all the reveiws that the 680 overclocks better with less power and more performance than the 7970

I can't believe video card fanboys actually exist.

I think Nvidia is just going to beat 'em again. AMD threw out their best and Nvidia dropped a "supposed-to-be 660" to beat it. So, it'll be interesting nonetheless, but hopefully we don't have to wait too long for AMD to come up with something so that we can see Nvidia's response sooner thumb.gif
