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

Benchmark Results: Sandra 2012 And LuxMark 2.0

For all of their alacrity in gaming, the Kepler-based GeForce products demonstrate an evolutionary step forward in FP32 throughput and a more jarring slow-down in double-precision floating-point math. Meanwhile, AMD’s GCN architecture propels Tahiti forward in compute workloads.

Sandra 2012 helps quantify AMD’s gains and Nvidia’s willing compromise. The only cards GeForce GTX 670 beats in floating-point math are older Fermi-based boards. Meanwhile, the new 670 takes last place in FP64.

Leaning on this diagnostic tool again shows us bandwidth between the GPU and its memory, along with throughput over the PCI Express bus. Extremely low data transfer numbers across the board represents poor performance from the X79 platform. Meanwhile, internal bandwidth reflects on the 384-bit aggregate memory bus AMD uses on its Radeon HD 7900-series cards, along with the 256-bit interface Nvidia’s employs on its GeForce GTX 600s. GeForce GTX 690 seems to break this test, returning a bad GP call.

Applying those theoretical numbers from Sandra to a real-world-based test like LuxMark paints a pretty telling picture. AMD’s cards absolutely dominate. The slowest, Radeon HD 6990, even manages to beat the fastest Nvidia board—ironically, the old GeForce GTX 590.

Truly, we’re interested to see how Nvidia plans to address compute on the desktop after making such a big deal about it last generation. Might the company have plans to sell you a separate compute-oriented upgrade?

    $400 is still too high for me... Waiting for something around $225

    The list of games is very unfair to AMD cards. Techpowerup's review, which featured a much longer list of games, had the Radeon HD 7970 faster than the GTX 670 at all resolutions 1080p and higher.

    Nvidia has had a big lead in Dirt 3 and WoW for a very long time. This skews the results.

    The GTX 670 is a fantastic card, don't get me wrong. Just pointing out that it's being slightly overrated here.

    Great Review Chris!!

    Though there isn't really a performance hit but it would be great to have seen the GTX 670 running at PCIe 3.0.

    I hate Nvidia and their supply and demand game ...it is obvious that they are just holding off the cards to inflate the prices...I'm going with AMD ....because I'm tired of waiting ...I'm not going to wait anymore ..

    Nice move nV , forcing AMD to drop their prices for entire lineup. A 7970 at $400 would be really awesome...

    Excellent review. I was waiting for this card to hit. Only a 4.5% difference between a 680 for almost 100 less? Yes please!

    I am not trying to sound bad, but AMD might have a real problem on their hands with this card as it is priced very competitively for what you get. Especially since it competes with AMD's flagship that's more expensive.

    The question is will it be in stock or will it be a rarity like their other Kepler cards?

    @godfather666 Unless you happen to play WoW or Dirt 3.

    This is the price war you were looking for.

    Wait ... will we see any stock this year ... or are these going to be as rare as the 680 / 690 / 6xx ??

    The 6 series NVidia cards ... the ghost cards.

    All hype ... no stock.

    Nvidia are pumping out the reviews and advertorials ... mostly the latter I see across the web.

    This rollut must be costing them a fortune.

    I hope it's getting them sales in the old stock ... thats the point ... isn't it??

    Wasn't this card supposed to compete with the 7870 and 7950 lol? It's ripping both of them to shreds and manaing to hold its own against the 7970 in most cases....... AMD has got a serious problem on their hands now, because this thing looks like the next 8800gt or gtx 460

    Wow, never thought I'd see a "Baby Got Back" reference on a GPU review.
