Sorry but this just looks like a troll thread tongue.gif
I want to know clock for clock too. The purpose of it is not to decide which GPU is better, but rather to tell which is better when they're both overclocked, like in individual cases. Yes, everybody know the 680 is better at stock.

Stock volts are 1112 in AB. For 1200 voltage is upped to 1174 (which is the stock voltage for most 7970s) and for 1260 voltage is 1225. For me in order to hit 1300 I have to set voltage to it's max 1300 level. It's stable enough to bench on there but I would never use it for every day gaming. In fact I have three OC profiles, 1125 stock volts, 1200, and 1260 with the voltages you see above. If I'm playing an easy game I'll lower it down to 1125.

My fan curve has a pretty slow rise. I keep it below 45 til it hits 80 C and then it rapidly goes up. In BF3 at 1260 the average temp seems to be about 81 degrees. Honestly though I don't play games all that much. If you'd like I'll take a screen with Afterburner in the top corner in BF to give you a good idea.
 


There are 3 stock voltage 1.049, 1.11, 1.159 volts, mine is 1.049 stock.  I can't hit 1200 MHz at stock 1.049v.  Keep that in mind, there are 3 different voltages running around.

 

After about 1250 MHz, the voltage requirement for the last 100 MHz, totaling about 1357, takes about +200mV for me.  Very inefficient at the end.

Add 1.174 too the list. I can do 1175Mhz on Stock voltages. I undervolted it to 1.125v and 1125Mhz


Edit: As far as the battle goes this is the Same as HD 6970 vs GTX570. There is no GTX580 this round. So AMD and Nvidia will need another card to determine victories.

From what I've seen briefly, a lot of the retail cards tend to top out around 1150MHz with the +50 boost (so 1200 turbo).

at stock volts they seem to be topping out around 1200mhz.

i love this thread, i just spent a while going thru it and the main fact everybody is missing is that this 680 is the gk104, it was designed to compete with the 7800s, not the 7900s that it is currently a match for.

then we have the fact that these early results from ln2 land are with early ic, not much binning has taken place yet so wait till k|ngp|n and the likes gets an above average sample, i hear zotac are binning their top cards for 2ghz boost, imagine how fast that will go under ln2.

and thats just the hardware, not mentioned that nv tend to take a couple of shots at the driver before they get it right. launch drivers aint worth a ****, give a couple of months and then look what each card is doing then and only then will it be a fair playing field.

Yeah it can compete with HD 7870 if AMD clocked it up 1.4Ghz,

That's why you got such great OC's you have the low voltage model. Wish I had it but I'm ok being in the middle. Way better then my absolutely awful 2500k.

I think people should just buy GPU whatever games that performs better.
I mainly play WoW and 7970 doesn't really perform well compared to nvidia GPUs, so I am going to get a gtx 680.

Oh absolutely, it does look like XFX is binning the Black Editions, not just flashing them with a "cool" bios.

Check out OBR's 3dmark 11 xtreme score, seems like hes purposly clocking the AMD lower (Why is everybody avoiding clock per clock) so it loses by a hair.. What would have made more sense is to run clock per clock, and reveal the REAL truth. not to mention, i have a feeling that the MSI isnt as loud as he makes it out to be.

http://www.obr-hardware.com/2012/03/best-oced-radeon-hd-7970-lightning-vs.html

Also note that the CPU score and combined score for the AMD is also lower.

The error in 3Dmark11 xtreme scores is around +-50 points overall, i have noticed this running many tests for 3dmark11 in my own review. So despite the clock difference, these cards are literally within error clock per clock, in 3dmark 11. (a benchmark that at first glance shows nvidia much further ahead when comparing stock 1100 mhz for gtx 680 vs stock 925 mhz for 7970)

Also he doesnt show the temperature of the gtx 680, he hides it in the msi afterburner screenshot. I am guessing ocd it is much hotter than the 7970, in accordance with all reviewers, despite the much lower power draw.
