Exactly. They need to open up the GPU voltage or the cards aren't going anywhere. There was mention of a 1.5V Vcore limit for a custom Zotac model, but that's all I've seen as far as AIB's making an "unlocked" card.

Just because they are spec'd @ 75W in no way prevents them from passing more power.
Now, improving the power stages, which includes the connectors, can, and does, help O/C'ing. Generally though it's not much except in extreme cases, LN2, for example. Having a 6+8 or 2x8 pin connectors is not going to open up some magical O/C'ing window.

No. Where do you see the wattage for the 7970 OC?
My bad, I looked it over so quick I missed that the 7970 was stock for power consumption. I expected 7970 OC numbers in there. It must be too early in the morning.
Exactly. You can see the hypocrisy of certain posters in this thread. When the GTX 480 was 10% faster than a 5870 but used 50% more power, power consumption and performance per watt didn't matter because it was faster. Now that nvidia finally has a card that isn't a performance/watt joke, suddenly power consumption is everything. Also note that a large part of the small wattage difference between the cards comes from the 7970 having more vRAM on board.
It's actually quite interesting to find that both 680 and 7970 end up ~ the same frequency once both are OC to their max. That says a lot about 28nm, we're hitting a wall at ~1.3ghz.
Unless you need DP performance, there's very few reasons to go with a 7970 over a 680 now since OC vs OC the 680 has heaps better perf/w.
Yes because I made it with knowledge that you first need to OC the 7970 for them to really even be comparable.
The 7970 gobbles up wattage like nobodies business when you oc/ov, unlike the 680 with it's inherited "limitations".
You seem to have a hard time reading his charts...
If you look at 1100MHz vs stock 680 you'll find his charts match up what you're showing.
135 fps 680 139 lightning...
125.9 fps 680 stock, 133 fps 1100MHz 7970.
Got anything else?
Don't try to completely twist this particular point. It is nearly the same argument now as it was when Fermi 1.0 came out. Then, AMD people cried out that power draw was important. Now, Nvidia people are crying out that power draw is important. Both camps argue power draw when it is in their favor. The big difference is that in both situations Nvidia has the faster GPU.
Imho,
To me, performance per watt was a nit-pick on Fermi over-all.
AMD, really had some strengths with a very balanced gaming architecture, with strong performance value and a commitment to the sweet sport with the 58XX series. So much competition that the 5XXX series helped propel AMD to over-all discrete leadership for a quarter.
However, Fermi had strengths, with performance, features and flexibility and was also compelling to many; and a more mature family top-to-bottom? nVidia started to separate once again on over-all discrete leadership.
nVidia's GK-104 offers a very balanced, very efficient architecture -- it's like what AMD did -- performance/dollar --- performance/watt ---- performance/nm --- but with many, many strengths of nVidia -- performance -- features --flexibility -- pro-active. The best of all worlds with less limitations and sacrifices -- and yet, even cheaper as AMD is not the King of Performance over-all but more-so, well, gamers have to pay more of a premium for AMD.
How things have changed up for AMD.
It was hardly a nit-pick if we are talking about the GTX480. Not only did that card launch to mostly poor reviews roasting it over the coals for power consumption, but moreso as a result of that, huge amounts of heat and noise. The card was plain obnoxious to run, came 6 months late and cost significantly more, for at the time, a very small performance lead over the 5870.
I think GTX680's characteristics are in part a direct reaction to the roaring Diablo that was GTX480 and Fermi. Even the 580 has pretty poor thermals and power consumption, it's not much better than the 480, apart from less noise.
Just can't take this statement seriously or as an objective one given your past post history. Too much harping on the 7970 over perf/$ and now trying to give the 680 that laurel ?
The 680 fails hard on perf/$ and your much trumpeted 'significant node change/arch' mantra. 30% faster than a 580 for the same price. The worst performance gain in a flagship from nvidia ever.
$50 less and 10% more performance is nothing to ignore, but going from that to the heap of praise you are trying to lay on the 680 in contrast to how you denigrated the 7970 is laughable.
I know you prefer nvidia, but try to stay consistent so your posts can be taken as an objective opinion, rather than a preferential one.
Small Performance Improvements or Small Overclocking Ability?
You will notice that we are really only seeing up to about a 15% or close to 17% performance improvement with the overclocked GTX 680 versus a stock GTX 680. That may seem low, especially when you consider the kind of percentages we see in improvement overclocking a Radeon HD 7970. However, the Radeon HD 7970 has a wider overclockable range than the GeForce GTX 680.

It is what it is. nVidia's flag-ship GPU offers more performance/dollar than AMD's - clearly
Now my view is this:
Considering the 28nm is substantial and significant from 40nm, the performance value of both the GTX 680 and HD 7970 are more-so evolutionary and incremental, when one looks at historical price/performance. As the constructive nit-pick on Fermi was performance/watt to me -- I feel performance/dollar for 28nm is the constructive nit-pick.
I tried to offer this same point about the HD 7970 but had such insane strong defense of premium pricing. And yet I say the same exact thing about the GTX 680 -- not a single cricket. I've been posting for over a decade and never have witnessed such irony in my posting life.

Also,
The gigabyte 680 OC / MSI lightning 680 version can't come soon enough. It looks like the 2x 6pin max TDP is a big factor preventing max overclocks.
I saw the TF3 version of the 680 but it doesn't have the lightning monkier - i'm not sure if it is 8 pin / 6 pin like the gigabyte windforce.
