The GTX 590 vs. the HD 6990 – only One is “the World’s Fastest video card”
Not long ago we reintroduced Nvidia’s “Tank”, the GTX 580/570, as a much leaner, meaner and faster machine – all the while improving on the thermals, power draw and noise of the reference GTX 480. The Tank refers particularly to Nvidia’s flagship video cards which are equipped to handle any gaming situation at high resolution and with maximum details and with maximum filtering and anti-aliasing applied. Today, we see Nvidia new $699 flagship released – Tank times two! – the dual GF110 GPU GTX 590 which is designed to take on AMD’s $699 flagship HD 6990.
Nvidia released its long awaited GeForce GTX based on its brand new Fermi DX11 GF100 architecture back in April of last year, six months later than AMD’s own DX11 Cypress video cards. This new Fermi GPU – Graphics Processing Unit – a term originally originated by Nvidia is a continuation of their strategy since their G80 which launched over three year ago to create a General Purpose Processor – co-equal with the CPU – that also renders amazing graphics. The culmination of Nvidia’s efforts with their GF100 DX11 Fermi architecture was the GTX 480 with the caveat that it runs rather hot and the cooling solutions based on the reference design were rather noisy.
Things changed very rapidly as Nvidia’s introduced a new refined GTX 400 series ‘Tank’, the Galaxy GTX 480 SuperOverclock on a mature process which we covered in this review. Shortly thereafter, enter the completely redesigned Nvidia Tank – at $499 suggested etail pricing and designed to be faster and more efficient than even the super-overclocked GTX 480s.
We saw AMD introduce their new line up, HD 68×0 series to replace HD 58×0 series in our review here. We found out that the “Barts” GPU it is based on is only a mid-range launch so far with the HD 6870 only slightly faster than the HD 5850; the best part is that it replaces it for less money. And at the end of last year we saw AMD’s Cayman release in the form of HD 6970 and HD 6950. Nvidia took aim at the HD 6970 with the GTX 570, and the GTX 560 Ti takes on the HD 6870 and the HD 6950.
In turn, AMD released their flagship dual-GPU, $700 video card a few days ago on March 8 and we reviewed it here. It absolutely blew away the GTX 580 and AMD’s own HD 6970 with the caveat that it is rather noisy under full load. Well, now Nvidia has just now releases their own dual-GPU graphics card, their flagship GTX 590. It boasts 512 CUDA cores each. That means two independent NVIDIA GF110 GPUs are internally connected to deliver 1024 total cores of processing power. The GTX 590 has six 64-bit memory controllers which make up the 384-bit bandwidth per each GPU. This is matched with 3GB of total GDDR5 video frame buffer – 1.5 GB per GPU just like two down-clocked GTX 580.
Here are the specifications for the GTX 590:
Since, Nvidia’s new GTX 590 now also comes with a MSRP of $699, which one is worth your hard earned dollars and are they worth the $700 that one would currently spend for a single video card?
To properly bring you this review, we are using our reference HD 6990 and HD 6970 which we put through their paces last week with the release 11.4 (beta) Catalyst drivers in the launch article. We are putting HD 6990 head to head in 28 modern games and in 3 synthetic benchmarks to see which card may be for you using 1680×1050, 1920×1200 and/or 2560×1600 resolutions. Since we are using fast single-GPU video cards, it makes sense to test them at the highest resolutions and with the most demanding playable settings that they can handle. Since we are matching the two top dual-GPU video cards to each other in a performance showdown, we do also include HD 6970 and HD CrossFire as well as GTX 580 and GTX 560 Ti SLI configurations to get an idea of value.
Before we do performance testing, let’s take a look at the original Fermi GF100 GTX 480 and quickly recap its new DX11 architecture and features of the original Fermi GF100 which we covered in our reviews of the GTX 480, published here, here and here. Senior Editor BFG10K reviewed GTX 470 here and here and Senior editor MrK covered GTX 465 here.
We also examined the performance of Galaxy’s GTX 480 SuperOverclock and we also reran GTX 480 against stock and overclocked versions of HD 5870, HD 6870 and HD 6850 here just a few weeks ago. A recent review covered the GTX 580 a few months ago. We also covered GTX 570 and the launch of the HD 69×0 series against GTX 460. And Senior Editor Leon Hyman covered GTX 460-768M vs. HD 5830 here last week. Now you are up to date.
Specifications
The GeForce GTX 590 is basically two GTX 580s on a single PCB. However, it was exceptional engineering feat to get these two very powerful GPUs into a single enclosure in a two slot video card that can handle the extreme thermals and wattage without sounding like a hairdryer.
Vapor Chamber Cooling
One of the reasons the GTX 590 is barely any louder than a GTX 580 – about on the same level as a HD 6970 – is because the thermals are tamed by Nvidia’s vapor chambers.
Here is a good look behind the fan.
Take a look at the coolers.
The GTX 590 was designed from the ground up to deliver exceptional tessellation performance, which is a key component of Microsoft’s DirectX 11 development platform for PC games. Tessellation allows game developers to take advantage of the GeForce GTX 590 dual-GPU’s tessellation ability to increase the geometric complexity of models and characters to deliver far more realistic and visually rich gaming environments. You will soon see that although the clocks of Nvidia’s GTX 590 are clocked far lower at 605/1707MHz than the reference GTS 580 version at 772/2001.
In our testing, we lowered the clocks of a pair of GTX 580s in SLI down to match the reference GTX 590 and we discovered that it generally used 150W less than the stock-clocked pair! And this was without even lowering the voltage. Of course, Nvidia has had quite a bit of time to tweak these cards and we find that the GTX 590 generally outperforms the underclocked GTX 580 SLI’s pair. We will draw attention to this in our regular testing of the individual games that we tested with underclocked SLI’s GTX 580s vs. GTX 590.
Of course, we know that GTX 580 SLI beats HD 6970 CrossFire and HD 6990. We do not know if the GTX 590 can manage the same feat as it rather underclocked. We also want to know if there is any more headroom to overclock it further; we suspect there is.
We see the new GPU supports the new HDMI 1.4a connector standard as there is one mini HDMI output and 3 DVI outputs. We can finally enjoy Nvidia’s Surround – their answer to AMD’s Eyefinity – on a single card. Unfortunately, we did not realize that all three displays must have the same native resolution, unlike Eyefinity which only requires that all three displays support a common resolution. Next time we will bring you Eyefinity vs. Surround.
Now lets compare the brackets and the connectors of the GTX 590 (above) with the HD 6990 (below).
The GTX 590 is much shorter than the AMD card and is physically able to fit in a lot more cases. No doubt the OEMs will really appreciate this.
Needless to say, the new Fermi Dual-GF110 GTX 590 brings a lot of features to the table that current Nvidia customers will appreciate, including improved CUDA’s PhysX, 2D and 3D Surround to drive up to 3 LCDs with a single card, superb tessellation capabilities and two really fast GPUs in comparison to their GT200 series and even their hot running GF100 series cards.
WHY choose a GTX 590?
Nvidia themselves believes that the GTX 590 is about 1.5 times faster than a single GTX 580. Since the GTX 580 retails for $500, the performance to value ration remains the same. Now you can even have ultimate performance with Quad-SLI – 2 times GTX 590 as long as you have the right motherboard.
Another reason to choose a GTX 590 would be where you only have one 16x PCIe slot available and you want the single fastest video card. Either the GTX 590 or the Radeon HD 6990 might fit the bill. But which one to choose? Read on.
Should you SLI your GTX 590?
If you have a top PC and $1500 to spend on graphics, you might consider Quad-SLI. It is supported by GTX 590 and there is improved scaling. There are also recently more compelling reasons besides increased performance to consider GTX 590 SLI which includes being able to experience Nvidia’s multi-display 3D Vision Surround. The only other way to experience similar but lesser performance is with 3 x GTX 580 Tri-SLI for about the same costs.
At this time, Nvidia does not support GTX 580 plus GTX 590 Tri-SLI although they could easily enable it in the drivers if they choose. It would give enthusiasts a cheaper way to experience Trr-SLI without a very expensive motherboard as the two card can be run together without a PCIe slot in-between as shown below. Notice the GeForce logo lights up on the GTX 590; a nice touch!
The GTX 580 was used with the GTX 590 as a dedicated PhysX card; the SLI bridge is only shown for illustration. Here is what the control panel looks like.
New Power Monitoring Hardware – or no more Furmark!
Nvidia has added a power draw limitation system to their card beginning with the GTX 580 and also with the GTX 570 and GTX 560 Ti. When either Furmark or OCCT are detected, sensors measure the incoming current and voltage to calculate the total power draw. If the power draw exceeds a certain predetermined limit, the GTX 590 will automatically downclock to avoid damage to hardware components. After the power draw drops back to safe limits, the GPU returns to normal clocks much the same as with thermal management.
Because of this, we will no longer use Furmark for showing power draw and will return to using games to illustrate real world situations. Currently, this power management only switches on when Furmark or OCCT are detected and it should not limit overclocking unless Nvidia extends this management to regular PC games. Evidently this works by having the GeForce driver detect the program and treat it as a virus. In the case of the GTX 580 and the GTX 590, this power limiting circuitry implementation is mandatory by Nvidia’s parners.
As a total package, the new GTX 590 looks (and sounds) great! It looks and feels solid. Let’s show you the results of our one day (yes, we got it yesterday!) hand’s on test drive, shall we? We will put it to the test in 29 PC games and in three synthetic tests. But first, head to the next page to check out our test bed configuration.
This review was so absolutely great. Miles above the Anand’s 10 games. I really really think you go above and beyond. One of the few places you can get a full review anymore. Such a great collection of data! Most sites do a handful of games and there is no way anyone could get a true picture. Most sites have diminished their launch articles to a point of incompleteness. Where one has to go somewhere else to get a full picture.
Apoppin, i know its a lot of work for you, but i commend you for your dedication to all the data. Yours again is the most useful especially on a card that is so close in performance to the competitors. I cannot thank you enough for a fantastic article!
Very nice in-depth review, bookmarking the site now! Thank you for your hard work!
I love ABT reviews. They always seem to be pretty fair when it comes to in-depth testing. Keep up the good work guys. Really. I mean that. I plan to work for one of the many review sites when i finish my CE degree, and ABT is high on the list.
I’m impressed that Nvidia beat ATI in cooling with their dual GPU. It’s usually the opposite.
It is nice to see the cost for both cards is about the same which gives more choices for the consumers to pick from.
Nice Job!
Also a small note:
When I click “View All” it doesn’t work, could you guys get it fixed?
Our web master is aware of this issue and is working on it.
Thank-you all for your comments!
The HD 6990 is honored under warranty by most vendors with the OC switch. So I’m quite puzzled why you OC’d the 590 and kept the 6990 the same.
If you want to see the HD 6990 tested with the BIOS position No. 2, please check out our HD 6990 launch article:
http://alienbabeltech.com/main/introducing-the-worlds-fastest-graphics-card-amds-flagship-hd-6990
The same settings were used and now you have both settings completely covered.
You will also note in the Performance Summary of this GTX 580 launch article that we pitted our overclocked HD 6990 (960/1390MHz) against our overclocked GTX 580 (690/1825Mhz)
I believe we covered all of the bases.
You pointed out that bios switch 2 was tested in another review. But that does not answer why it was not tested in this review side by side with the 590(I hope that was not your answer as to why). Just saying it’s a bit weird you throw in a bunch of old games one being from 2005, but not test something most 6990 owners would be using.
BIOS position No. 2 was tested in the review immediately preceding this one and anyone can easily check the performance difference:
http://alienbabeltech.com/main/introducing-the-worlds-fastest-graphics-card-amds-flagship-hd-6990
The launch article about the GTX 590 tested the stock GTX 590 against the stock HD 6990. Then we tested the overclocked GTX 590 and the overclocked HD 6990 – both overclocked as far as they would go – the 6990 being overvolted in the BIOS No. 2 position and the GTX 590 at stock voltage.
Including a third set of Radeon slightly-overclocked numbers would have cluttered the charts and taken precious extra time that was spent in benching. Especially because these figures are easily found in the previous article that were tested at the same settings and with the same drivers.
We don’t “throw in” a bunch of old games at random. We have been following many of these games for nearly three years – when some were only a couple of years old and many top cards struggled with them – and our regular readers appreciate it. We also include a good mix of new games and are always adding more. Next added will be Bulletstorm and Shogun 2 and of course Crysis 2 when it fully debugged and running on the DX11 pathway.
magnificent review
This wasn’t a terrible review but it was definitely biased towards nVidia.
In the Metro 2033 section you actually claim that the GTX 590 “Beats” the Radeon 6990 with 39.48 FPS vs. 39.2 FPS. You even used an exclaimation point!
Comparisons within 3-6 FPS are inconclusive, let alone 0.3 FPS! Calling that any kind of defenative win is just absurd and proves you’re milking every possible edge the 590 might have.
Don’t get me wrong; I’m using an nVidia card right now (Good ol’ GTX 460 SC) but I appreciate that both companies make stellar cards and it’s only fair to try and be unbiased as a reviewer since GPU consumers tend to be so polarized.
Ultimately nVidia tends to have a slight performance edge and AMD tends to have a price edge. The only things that really make each company’s cards unique are special features like CUDA and Eyefinity.
I dont think the 590 or equivelent is such a big step from the card I have (the 480) for me really to be that excited.
The step from 8800gtx to gtx480 was a really huge step tho (3x the improvement) like this is more like .5x the improvement, so I dont really give a shit.
Sorry for mentioning all those nvidia cards, but its what I purchase, I work with CUDA for my gpgpu programming, so maybe even im a little biased, but opencl is what you use for amd cards, and its just as good.
Way too many comparisons of other GPUs, it’s 590 vs 6990, remember? I was all confused with the color schemes on the graphs.
I know quite a little about gfxcards so I didnt find answers why nVidia is better in some games and AMD in other games? Directx vs opengl? I play only Waw, BO, ET and Brink so I still dont know do I buy next 580, 590, 6970 or 6990. I have now 570 SLI but somehow my computer doesnt work well when SLI is on so single card is the solution. But which one?
I would highly recommend that you ask you question in our forum. You will get good information there and far more detail than from comments here.
SLI should work well if you have a SLI MB. And there are many reasons why Nvidia is better in some games and AMD in others.

Would it be possible to get a copy/screenshots of the current bios setting using during the tests?
Wicked not biased review. Not.
what kind of a joke is this? , we are compareing over all proformance , why the HELL is phyx disabled ? , it is fair because its an official feature of nvidia , if amd does not have it , its not nvidias fault , we want an answer , it looked like u guys wanted nvidia to look slow or someting ?
There is no other way to compare performance directly.
How many PhysX games are we comparing? Two out of nearly thirty games. Just ignore those results and look at the rest of the review. We test about 3 times more games than any other tech site.
@najeeb what kind of joke are you on about? physx makes Nvidia cards slower in performance if turned on, if physx was on it’d be unfair to Nvidia right? In your case you should say “It actually seems like they’re trying to make Nvidia cards look faster than the AMD counterparts by disabling certain features.”
Wow that was extremely bias. Xbitlabs.com comparison was perfect.
I just watched an youtube video comparing both cards and Radeon uses a lot less power from psu and gave a better or equal fps result than Nvidia. Others reviews compare both cards to be equivalent. I think this review is very outsiders and biased.
Definitely appreciate you discussing this article. Great!!
I certainly enjoyed the way you explore your experience and knowledge of the subject! Keep up on it. Thanks for sharing the info!
Can anyone able to recommend comprehensive Rice B2B Database? Thank you 😀
