Correct, having said that how much power do you save when your GPU goes from 80C to 75C?
Correct, having said that how much power do you save when your GPU goes from 80C to 75C?hey janoo i disagree with keys 9 times outa 8, but hes right about temps and power. not saying you are wrong, but i wouldn't immediately discredit his statement.
1.2v gpu at 30C liquid is going to use less power than the same 1.2v gpu with the block off on an air cooler running at 90C.
I remember yesterday there was somebody here who questioned the ability of the GTX680 to run games on 1300MHz core (stock cooling). Well, here it is:
Clock speed alone doesn't mean much, whats important is how well does it scale per MHz? So far it doesn't seem to scale as well as i'd like. The most i've seen on websites is 15% with a 150mhz offset, which is less than how well the 7970 scales with higher clocks.
In my own testing i'm not gaining much with a 100mhz offset. I gained about 3 fps in crysis 2, i'm not sure if this is attributable to early drivers or beta overclocking software or what.

Subject: Kepler Rising
Today, the first Kepler - GTX 680 - is on shelves around the world!
Three years in the making. The endeavor of a thousand of the world's best engineers. One vision - build a revolutionary GPU and make a giant leap in efficient-performance.
Achieving efficient-performance, great performance while consuming the least possible energy, required us to change our entire design approach. Close collaboration between architecture-design-VLSI-software-devtech-systems, intense scrutiny on where energy is spent, and inventions at every level were necessary. The results are fantastic as you will see in the reviews.
Kepler also cultivated a passion for craftsmanship - nothing wasted, everything put together with care - with a goal of creating an exquisite product that works wonderfully. Let's continue to raise the bar and establish extraordinary craftsmanship as a hallmark of our company.
Today is just the beginning of Kepler. Because of its super energy-efficient architecture, we will extend GPUs into datacenters, to super thin notebooks, to superphones. Not to mention bring joy and delight to millions of gamers around the world.
I want to thank all that gave your heart and soul to create Kepler. You've created something wonderful.
Congratulations everyone!
Jensen
Maybe you'll have to play more with them or it depends on games. I see here good scaling:
An overclocked GTX680 gets better minimums that the average 7970 OCed.
Anyone get theirs yet and use Evga precision to boost TDP to +50%?

Yeah i'm going to fiddle with that a bit. Thats quite opposite of Fermi where memory had little impact, whereas GPU clock made a major difference....of course the memory controller on Fermi was semi broken.
None of this is meant as a slight to the 680, i'm extremely impressed with the stock speed, and the quietness of the card..... but the overclocking situation leaves a sour taste in my mouth. I'm going to wait for a few more rounds of driver updates, or maybe its a BIOS issue. Its just one of those things you deal with as an early adopter I guess.
What drivers are you using ? The 300.99 or 301.10 ?
I also second OCing the memory. Card could use more memory bandwidth and some reviewers said they saw bigger gains from memory than core.
Some of the poor results in some games and better in other could be drivers. The card is just out and I'm sure BF3 would be one the games that got the most attention driver wise.

Do you get uneven clockspeeds between gpu 1 and gpu 2?
Here's the missing bit of that email:
"Props go out to our loyal fanboys and fangirls for keeping it together during these past couple of months. Your efforts at whining about the 7 series cards' prices and performance increase are appreciated. We know you are willing to pay a premium for nV cards and we have given you exactly that! If you think the GTX680 is great...just wait until we bring you the REAL high end.
ARE YOU READY?!!!!!!!!!!
Your bestest friend,
JHH"
Didn't know that also AMD fanboys get mails from Jen Hsun. Aparently he sent you one.

You can't do +50%. You can do 132% of TDP with EVGA precision X, which AFAIK is the only app that works with the 680...
So far i'm using 132% power limit, with 100mhz offset and 100 mhz memory offset. If I go higher than that I get tons of TDPs.
Afterburner doesn't work (even the latest beta)
I think it does depend on title. What I noticed is that GPU boost produces different max clocks depending on game, for instance in bf3 my GPU clock is 1258 and GPU2 is 1245. But if I play crysis, they're slightly lower. BF3 is one of the best titles on the 680 right now with outstanding sli scaling.
VERY weird.
Did you see the 7970 beating 680 SLI on that review in high-res BF3? Also where is that 1335 core 680 review from? The asus 680 review from vrzone?
