GeForce GTX 670 2 GB Review: Is It Already Time To Forget GTX 680?

EVGA GeForce GTX 670 Superclocked

Although Nvidia is making its GTX 670 reference design available to add-in board partners, it expects to see a number of custom implementations right out of the gate as well. 

EVGA sent us its GeForce GTX 670 Superclocked, which actually employs the same reference dual-slot form factor, but features elevated core (967 MHz), GPU Boost (1046 MHz), and memory (6210 MT/s) frequencies.

At its stock clocks, EVGA’s board offers a nice little performance bump. You can expect to pay £330 for that boosted model—a £10 premium over the regular model. Many enthusiast won’t be willing to spend the extra money, since the Superclocked card’s overclock is probably well within the reach of manual tweaking. However, the security of EVGA’s three-year warranty on a factory-overclocked component will undoubtedly satisfy risk-adverse gamers who don’t want to bother tweaking on their own.

Interestingly, though, EVGA has a couple of other SKUs planned: a GeForce GTX 670 4 GB and a GeForce GTX 670 4 GB Superclocked.

We know a number of other vendors also have 4 GB models in the works, and the picture of the back of the GeForce GTX 670 PCB on the previous page makes it clear that there are pads on Nvidia's design just waiting for more memory.

Notice that the PCI Express bus is still running at second-gen transfer rates. The same X79-based issue that kept Nvidia from enabling PCIe 3.0 on the GeForce GTX 680 affects the 670, too. For a more thorough explanation (or at least, a more direct hint, I should say), check out page three of GeForce GTX 690 Review: Testing Nvidia's Sexiest Graphics Card.


Of course, enthusiasts who are willing to get their hands dirty can take the GeForce GTX 670 Superclocked and apply EVGA’s superb Precision X utility to it. The recently-updated software facilitates manipulation of Nvidia’s power target, GPU and memory clock offsets, the card’s voltage, and fan speeds. Built-in monitoring makes it easy to keep tabs on power as a percent of rated TDP, clock rate (affected by GPU Boost), and several other variables.

We were able to take the already-overclocked EVGA even higher with a +75 MHz GPU offset and a +50 MHz memory offset, aided by a +22% power target, taking the board power up to about 173 W. At those frequencies, Precision X was reporting core clocks up to 1228 MHz and memory data rates of up to 6302 MT/s.

In most applications, that was good enough to land the overclocked EVGA card in between its already-tweaked stock clocks and a GeForce GTX 680. In a couple of others, the overclock yielded better frame rates than a stock GeForce GTX 680, even.

    I really think AMD should of set the 7970 clocks higher at default. Any 7970 owner knows with their card at 1125/1575 its much faster than the GTX 670 but this review paints a very different picture.

    Shut up and take my money, NVIDIA!

    AMD probably have very good reasons for keeping their cards at that level. I mean, if they could release them factory overclocked, they would be doing it as fast as they could, as it would give them a huge edge.

    gtx 670 and 680 performance is too similar !!!!! 680 is pointless !!!! don't buy it !!!

    Great job with the relative performance % charts on page 15 - would be great to start seeing this in all graphics card reviews (for example the upcoming GTX660 review comparing with GTX570 and GTX670!). Also good job re-running the numbers on all three GTX600 cards with the fresh drivers.

    You should be aware though when talking about availability issues that these don't necessarily apply to all markets. Over the past couple of years (since GTX470/GTX480) launch, I've observed quite a few cards with apparently poor availability actually being very easy to get hold of in the UK. Maybe it's easier to cater to the graphics needs of 60 million people than of 300 million :-) Something to keep in mind anyway.
