In a typical high-end GPU launch we’ll see the process take place in phases over a couple of months if not longer. The new GPU will be launched in the form of one or two single-GPU cards, with additional cards coming to market in the following months and culminating in the launch of a dual-GPU behemoth. This is the typical process as it allows manufacturers and board partners time to increase production, stockpile chips, and work on custom designs.

But this year things aren’t so typical. GK104 wasn’t the typical high-end GPU from NVIDIA, and neither it seems is there anything typical about its launch.

NVIDIA has not been wasting any time in getting their complete GK104 based product lineup out the door. Just 6 weeks after the launch of the GeForce GTX 680, NVIDIA launched the GeForce GTX 690, their dual-GK104 monster. Now only a week after that NVIDIA is at it again, launching the GK104 based GeForce GTX 670 this morning.

Like its predecessors, GTX 670 will fill in the obligatory role as a cheaper, slower, and less power-hungry version of NVIDIA’s leading video card. This is a process that allows NVIDIA to not only put otherwise underperforming GPUs to use, but to satisfy buyers at lower price points at the same time. Throughout this entire process the trick to successfully launching any second-tier card is to try to balance performance, prices, and yields, and as we’ll see NVIDIA has managed to turn all of the knobs just right to launch a very strong product.

Like GeForce GTX 680, GeForce GTX 670 is based on NVIDIA’s GK104 GPU. So we’re looking at the same Kepler design and the same Kepler features, just at a lower level of performance. As always the difference is that since this is a second-tier card, NVIDIA is achieving that by harvesting otherwise defective GPUs.

In a very unusual move for NVIDIA, for GTX 670 they’re disabling one of the eight SMXes on GK104 and lowering the core clock a bit, and that’s it. GTX 670 will ship with 7 active SMXes, all 32 of GK104’s ROPs, and all 4 GDDR5 memory controllers. Typically we’d see NVIDIA hit every aspect of the GPU at once in order to create a larger performance gap and to maximize the number of GPUs they can harvest – such as with the GTX 570 and its 15 SMs & 40 ROPs – but not in this case.

Meanwhile clockspeeds turn out to be equally interesting. Officially, both the base clock and the boost clock are a fair bit lower than GTX 680. GTX 670 will ship at 915MHz for the base clock and 980MHz for the boost clock, which is 91MHz (9%) and 78MHz (7%) lower than the GTX 680 respectively. However as we’ve seen with GTX 680 GK104 will spend most of its time boosting and not necessarily just at the official boost clock. Taken altogether, depending on the game and the specific GPU GTX 670 has the capability to boost within 40MHz or so of GTX 680, or about 3.5% of the clockspeed of its more powerful sibling.

As for the memory subsystem, like the ROPs they have not been touched at all. GTX 670 will ship at the same 6.008GHz memory clockspeed of GTX 680 with the same 256-bit memory bus, giving it the same 192GB/sec of memory bandwidth. This is particularly interesting as NVIDIA has always turned down their memory clocks in the past, and typically taken out a memory controller/ROP combination in the past. Given that GK104 is an xx4 GPU rather than a full successor to GF110 and its 48 ROPs, it would seem that NVIDIA is concerned about their ROP and memory performance and will not sacrifice performance there for GTX 670.

Taken altogether, this means at base clocks GTX 670 has 100% of the memory bandwidth, 91% of the ROP performance, and 80% of the shader performance of GTX 680. This puts GTX 670’s specs notably closer to GTX 680 than GTX 570 was to GTX 580, or GTX 470 before it. In order words the GTX 670 won’t trail the GTX 680 by as much as the GTX 570 trailed the GTX 580 – or conversely the GTX 680 won’t have quite the same lead as the GTX 580 did.

As for power consumption, the gap between the two is going to be about the same as we saw between the GTX 580 and GTX 570. The official TDP of the GT 670 is 170W, 25W lower than the GTX 680. Unofficially, NVIDIA’s GPU Boost power target for GTX 670 is 141W, 29W lower than the GTX 680. Thus like the GTX 680 the GTX 670 has the lowest TDP for a part of its class that we’ve seen out of NVIDIA in quite some time.

Moving on, unlike the GTX 680 launch NVIDIA is letting their partners customize right off the bat. GTX 670 will launch with a mix of reference, semi-custom, and fully custom designs with a range of coolers, clockspeeds, and prices. There are a number of cards to cover over the coming weeks, but today we’ll be looking at EVGA’s GeForce GTX 670 Superclocked alongside our reference GTX 670.

As we’ve typically seen in the past, custom cards tend to appear when GPU manufacturers and their board partners feel more comfortable about GPU availability and this launch is no different. The GTX 670 launch is being helped by the fact that NVIDIA has had an additional 7 weeks to collect suitable GPUs compared to the GTX 680 launch, on top of the fact that these are harvested GPUs. With that said NVIDIA is still in the same situation they were in last week with the launch of the GTX 690: they already can’t keep GK104 in stock.

Due to binning GTX 670 isn’t drawn from GTX 680 inventory, so it’s not a matter of these parts coming out of the same pool, but realistically we don’t expect NVIDIA to be able to keep GTX 670 in stock any better than they can GTX 680. The best case scenario is that GTX 680 supplies improve as some demand shifts down to the GTX 670. In other words Auto-Notify is going to continue to be the best way to get a GTX 600 series card.

Finally, let’s talk pricing. If you were expecting GTX 570 pricing for GTX 670 you’re going to come away disappointed. Because NVIDIA is designing GTX 670 to perform closer to GTX 680 than with past video cards they’re also setting the prices higher. GTX 670 will have an MSRP of $399 ($50 higher than GTX 570 at launch), with custom cards going for higher yet. This should dampen demand some, but we don’t expect it will be enough.

Given its $399 MSRP, the GTX 670 will primarily be competing with the $399 Radeon HD 7950. However from a performance perspective the $479 7970 will also be close competition depending on the game at hand. AMD’s Three For Free promo has finally gone live, so they’re countering NVIDIA in part based on the inclusion of Deus Ex, Nexuiz, and DiRT Showdown with most 7900 series cards.

Below that we have AMD’s Radeon HD 7870 at $350, while the GTX 570 will be NVIDIA’s next card down at around $299. The fact that NVIDIA is even bothering to mention the GTX 570 is an interesting move, since it means they expect it to remain as part of their product stack for some time yet.

Update 5/11: NVIDIA said GTX 670 supply would be better than GTX 680 and it looks like they were right. As of this writing Newegg still has 5 of 7 models still in stock, which is far better than the GTX 680 and GTX 690 launches. We're glad to see that NVIDIA is finally able to keep a GTX 600 series card in stock, particularly a higher volume part like GTX 670.

    Massive smackdown, lol it made AMD lower it'S prices by 50-60$, that's not massive.

    You know what's massive, my two radeon 6870 that I paid 130$ each and still compete with those 400$ cards... That's a massive smackdown because I bought them almost A FREAKING YEAR AGO. Take that abuser of the word ''massive'' :P

    I very recently ( a couple months ago) recommended a 6870 to a very close friend, I think the price was about $159 and it had maybe some rebate at the egg.
    He bought it and has been running it for his several sims, it was the best bang for the buck at the time in a level above his then current 3 or 4 running vid cards ( 4000+5000 series).

    So no doubt amd can have a deal worth purchasing, it's just not there at all in these 2 new generations. Not even a tiny bit.

    And what's the reason for that, do you know? It's not because Nvidia IS SO FAR SUPERIOR ffs stop with that, it may be superior but it's not a civic vs a ferrari. AMD had the price/performance/die size superiority because they'Ve been doing(since radeon 4870) a shift in making the most heavy gpus in the world.

    Nvidia was focusing on a more computationnal approach and biggest gpu, strongest performance since... well since it's alive I think. Nvidia simply took AMD's way for this gen, forget about compute power a little and focus on smaller die for mazimum performance and low consumption while AMD made the move the other way, improved their compute power at the cost of die size and power consumption.

    That's what GCN is all about. it'S about the same thing that happened with GTX 2xx vs radeon 48xx cept that 4870 was more than TWICE smaller than GTX 2xx and almost as performant and sometimes even more. Not a mere 43% difference in die size, MORE THAN DOUBLE the size and still were so close in performance.

    And why am I doing this analysis and you didn't, because you were too much occupied at launching inflammatory disrespectful stuff, like lots of nvidia fanboys do. People don't deserve this in a ''computer part'' oriented discussion. You were at the same time saying people were stupid and disrespectful while you were doing the same, let's say even worse.

    Now get a neutral vision of things before commenting like you do, you wanna be a fanboy, at least do it in the light of respect. Did I call you any names now? Did I have to use the words ''stupid'', ''analphabet'', ''dumbfuck'', and so on... No because that was meaningless. Learn from the best of die like the rest.

    Yes you're a smack talker name calling disrespectful jerk.

    Yes of course you did, and you're a red fanboy and angry about all my absolutely valid points.

    That wall of text you have there is a big zero of hate - some toward me, so playing some innocent jay card doesn't work either, and BTW you've now posted a curse word, something I have never done.

    So you're a garbage mouth, and very disrespectful.

    I never called you any names NEVER look at all my posts, I never called you even one name and you just did it again and again but I'm the one who lacks respect what's that:

    ''disrespectful jerk.''
    ''you're a garbage mouth''

    That word I posted was an example, it wasn't meant toward anyone it was an example.

    PS
    angry disser Galidou " And why am I doing this analysis and you didn't, "

    Why you are doing this analysis is because you are a pure amd troll and have to go back to the last generation to try to make some idiotic historical point because you have no current points and no current rebuttals.

    Furthermore you claim I am somehow unsound by not having made your crybaby last generation whining no real point but I have made the more pertinent point as nVidia beat amd in every single metric here.

    I guess for your "win" you need to squeal about respect as you do the same trash talk, then go back to a prior generation to try to whine about what exactly ?

    You having a neutral vision is one big fat joke.
    You're in with all the amd fanboys here telling lies and going back a generation and whining about that...

    It would be nice if your snide remarks could be directed at pertinent points I have made but so far you're incapable, and often just on a troll attack against me personally in at least two of your other posts.

    What were you spewing about up there anyway ? Power ? LOL
    Guess who loses that sonny.

    these are the words you currently used in about 4-5 posts of yours, I don'T want to make any point with you toward video cards related discussion because of that, these are the words you use, I just want you to realize what you do:

    ''pathetic amd fanboys
    massive ignorance
    disrespectful jerk
    smack talker
    angry disser
    you're so ignorant
    most ignorant and clueless fools
    Where exactly is the brain ?
    (roll eyes at the immense ignorance, again)''

    and then at the same time use a sentence like:

    ''Thank me when you grow up enough to realize rebutting lies and fibs by others is an adult and responsible''

    The attitude words you used up there are so responsible... but no, you could just make your point and end it with a ''.'' but you ahve to add those words attacking everyone in your way, but sorry I forgot, I'm the one who attacks you, you're the perfect one... I'm maybe a troll but I'm not mad like you are.

    But hey, your arguments are so right that you gotta use all this stuff in your argumentation and call everyone a mad hater. Who's the hater? I already like Nvidia I'm no AMD fanboy.
