GTX 670 SLI Results

Arctic cooling is releasing a closed loop GPU water cooling. Get that instead of custom water. Much safer and probably no leaks either

I will check that.I was also eying the XPSC ones.

I think after my failed experiment with 4870X2 and Gtx 470 SLI I am going multigpu again

I've had tremendous multi-gpu success with nVidia the past couple years. Good choice.

 

[aaksheytalwar]

But if you want multi GPU, avoid CF as SLI is smoother for that

Its 200 dollars and a huge waste

 

[aaksheytalwar]

200 dollars is still cheaper than custom and far safer and easier to install

Drooling over the 670 right now. Going to SLI them in my main rig at release. The 460s have served me well!

You will more than double your performance stock to stock

Guys have been modding the self contained water cooling units and the results have been pretty good. GPU's respond very well to water cooling, but $200 is a pretty huge cost for a self contained unit, in my opinion. You can build a custom kit just for your GPU for roughly the same price, with the added versatility of being able to throw in your CPU.

Anyway, this card is on fire, very close to my 680. I haz a sad... lol

That 670 is oc'ed past 680 levels. Not really surprising. 670OC = 680, 7950OC = 7970, GTX 570OC = 580, etc. This has happened for a long time.

Why should AMD drop their price against these Nvidia Vaporware?

The 680 may be near vaporware but the 670's (if as expected) are the lower binned chips that didnt make it to the 680 cut, should be more widely available.

I think NV had stated some time back (despite all their bitching and complaining) that the 28mm yields were not as bad as fermis initial run.

This.

Again, ipc 680 > 670 perhaps

 

[chimaxi83]

Yea, from all the info I've seen so far, 670 looks to be hitting 1300+ with ease, which will push it past 680. My 680 tops out at 1270, which is still pretty decent, I guess

 

[aaksheytalwar]

Those are custom 670s not reference

And? Custom 680's released so far have done nothing for overclocking, so these 670's being custom is irrelevant. They're just good overclockers like some 680's are.

I dunno about 1300. My 680s couldn't go past 110-120 or so offset, and in sli they had uneven boost speeds. During gaming they got up to around 1200ish. In any case, the reference 670 will perform probably 10% less and have less OC headroom - because it will have only a 4 phase VRM and 2 x 6 pin power.

Obviously, a highly customized non reference 670 will have the potential to perform like a 680. Thats what these benchmarks are based on, a super charged 670 with a special cooler and non ref card. Not surprising.

Custom 7970s were $580-600 not long ago. 4 months later we are about to get similar performance for possibly $430. :thumbsup:

 

[aaksheytalwar]

Do you remember 480 and 6970 or gtx 285 and 5870?

The vast majority of your posts is "This", why? Add to the discussion or stop fluffing your post count dude, there's a nef thread for that

Anyway, I know what you're saying Blackened, but what I'm saying is so far, all this overclocking has been luck of the draw. My Gigabyte reference maxes at about 1270 on water, with nice 35-38C load temps. My girls TFIII 680 maxes at 1225. Others on overclock.net max at 1340-1350, on air, almost all of those being reference, 4 phase VRM, voltage locked cards. None of these "custom" cards do anything special, so far. That's why voltage adjustable cards like Asus DC II and EVGA Classified are coming out, I'd consider those cards true custom versions. Hell, even MSI's Twin Frozr 680 doesn't do anything special, as far as clocks.

I think people are jumping the gun by thinking all 670's will perform like this one leaked unit. Just like with the 680 reviews, the review sites all got great OC's. But then you read on forums and a lot of people got nowhere near what the review sites saw.

If these chips truly did not make the cut as a 680, I don't see the logic in assuming they will all somehow have the same performance. If they truly did run just as cool and reliably as a 680 chip, they would have become 680 chips.

It also seems very odd to me that nVidia would shoot their own foot off by making a 400 dollar card perform like a 500 dollar card.

I agree with you. The idea of the "custom" cooler is that the specialized cooler gives you a better chance of a higher, stable overclock. In practice, it doesn't do much except (1) cost you more (2) run at a different decibel level (usually lower) and (3) shave a few degrees off your GPU. I've never had a custom cooler that blows the doors off a reference card when both are good overclockers.

 

[aaksheytalwar]

Better vrm cooling and phases do help to some extent

 

[Destiny]

If these performance results are true and if it is true that these are binned GTX 680s...

I see more people doing SLI GTX 670s than going with a single GTX 690...

 

[Jaydip]

People who go for 690 will still go for 690 though
