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.

    lol twist the words any way you want. They will never mean what you want them to mean.

    The 7970 came out at 570$ and I didn't think it was a bad value. But at the same time its no 2900XT or 5800ultra.

    Right now I do feel Nvidia offers a better value. But their are situations, in very high resolutions and on certain games that AMD performs better. Why you cannot see that Nvidia isn't total domination is beyond me.

    You are correct I did twist them, on purpose.

    Thanks for actually noticing. Note also I didn't twist like that in my other posts.

    ROFL - your welcome.
  • CeriseCogburn - Sunday, May 13, 2012 - link

    PS- even though twisted, my point is still 100% valid, and negates the whole pile from chizow, so it means exactly what I said it meant, but putting two and two together is not your strong suit.

    You went from 5870, skipped the crappy 6970 generation, die shrink, core jump, because it sucked.

    You also passed over the overpriced amd 7970.

    chizow whines a lot, but you proved him wrong, and used the method I outlined and said most would do and most owning cards have done, not his stupid retentive one upgrade path only dumb as heck complaint.

    Dude, just sell the 560 and get the 670 - you can stop the cheetos binging and 2x2liter nighttime soda guzzling to make up the difference. Ebay is your friend. Reply

    And what's that supposed to prove? There are many games that use HBAO and FXAA, does it mean they are all botched?

    Disable them both and run the benchmarks. The difference would be none.

    Take unreal 3 for example. Let's say it favors nvidia. If so, then how come bulletstorm runs better on 7970?

    With nVidia card you can just use the upcoming automatic game settings - another gigantic nVidia driver advantage over amd's crap.
    It's getting far too embarrassing to support amd's crap anymore - there are now numerous absolute fails on amd's part.
    It was bad enough when amd didn't pay for PhysX, failed to have openCL in the drivers, had 3 features unchecked in gpu-z that nvidia had covered, failed in DX11 tessellation, was still plagued by the all in wonder corner mouse cursor bug from win98, had no ambient occlusion, cannot support cards going back to the equivalent of nVidia 8 series - but now they're so hammered by so many nVidia advantages beyond all those issues it is embarrassing to the point of humiliating.
    No adaptive v-sync now enabled all the way back for nVidia 8 series
    No frame rate target
    No on the fly power saving adaptive OC.
    No 4th monitor for surfing next to the surround eyefinity triples
    No driver present taskbar centering for triple monitor (addon amd)
    No sneak peek bezel driver support
    I'll stop because the list is so enormous now - and amd cannot even get working CF drivers going yet for half the games, while nVidia releases with SLI mastery.
    NVidia is in a superior position across the board - price, performance, power, drivers, added features, extra features, game day driver releases, and soon a driver optimizer (June ) that they make with their GPU server farms - actually pumping out the work for the gamer - something the embarrassed amd I guess is entirely absent on - while they fire more and more employees - making any sane person clearly see why the drivers that were already suffering are now even worse.
    AMD needs to be about half the price of nVidia hardware.

    ...except that nvidia can't seem to make more than a few dozen at a time.

    It's pathetic that they're pricing the only two GTX600-series cards to undercut AMD, yet they can't seem to build them. Pretty clever marketing gimmick. You price cards so they undercut the competition, and everybody salivates at the prospect of buying one and decides not to buy the AMD card... except they're not really available. Pretty cheap ploy from one of the most hated companies in the business.

    I'd be surprised if half of nvidia's board partners didn't go out of business or jump ship to AMD after this supply fiasco.

    This is the 3rd gtx600 series cards, but expecting you to be correct is worse than betting on the broken watch.
    GTX680 at newegg has outsold the entire amd 7870 and 7850 line up.
    Maybe your bean counting should be directed to the corporate pig loser amd ?
    At least with nVidia the partners can unload a million backorders when the supply irons out, and 2.5 months after release amd's finally ironed out... it was pathetic until then, so the very thing you spew about partners bailing already happened to amd right ? I mean let's keep your insane spewing consistent across the competition, why not that would be fair..
    Congratulations on being so incapable of making a point.
    nVidia's partners are counting the backorders and cannot count that high, now they have the even more impressive and winning GTX670 to unload - destroying amd's entire top line.
    What were you saying about nVidia partners ? Did your "unconscious" amd inner fanboy totally go bonkers and into insane projection mode ?
    It's amd partners that are in trouble now.

    Do you get payed for nVidia for posting crap like that or do you work at nVidia?

    So much idiotic hate towards a company that wasn't cought doing half of the shit, that nVidia did.
