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

Not like it was ever really widely available anyway, right? The GeForce GTX 670 offers most of GK104's on-chip resources, doesn't give up much performance, and costs £100 less. Now, let's see if Nvidia can make enough of them to satisfy demand.

When GeForce GTX 680 launched, we uncovered a bug in Nvidia’s driver that failed to accelerate transcoding of MPEG-2 sources using the NVEnc fixed-function logic built into GK104. A subsequent driver update was supposed to solve it, but a follow-up test revealed no improvement. Nvidia suggested that the shaders were handling the workload more effectively than NVEnc in our specific workload.

But retesting with 301.33 does alter the performance picture—both for the GTX 680 and 670. Now, a benchmark that took more than a minute on the Radeon HD 7900-series cards (which still can’t utilize AMD’s VCE technology, by the way), wraps up in roughly 30 seconds.

The H.264-encoded source we used for our GeForce GTX 680 review worked fine. Not surprisingly, then, the new driver and new card don’t affect performance. The task takes just 18 seconds now, as it did before.

    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.

    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.
