NVIDIA’s GeForce GTX Titan Review, Part 2: Titan's Performance Unveiled
by Ryan Smith & Rahul Garg on February 21, 2013 9:00 AM ESTFinal Thoughts
Bringing things to a close, most of what we’ve seen with Titan has been a long time coming. Since the introduction of GK110 back at GTC 2012, we’ve had a solid idea of how NVIDIA’s grandest GPU would be configured, and it was mostly a question of when it would make its way to consumer hands, and at what clockspeeds and prices.
The end result is that with the largest Kepler GPU now in our hands, the performance situation closely resembles the Fermi and GT200 generations. Which is to say that so long as you have a solid foundation to work from, he who builds the biggest GPU builds the most powerful GPU. And at 551mm2, once more NVIDIA is alone in building massive GPUs.
No one should be surprised then when we proclaim that GeForce GTX Titan has unquestionably reclaimed the single-GPU performance crown for NVIDIA. It’s simply in a league of its own right now, reaching levels of performance no other single-GPU card can touch. At best, at its very best, AMD’s Radeon HD 7970GE can just match Titan, which is quite an accomplishment for AMD, but then at Titan’s best it’s nearly a generation ahead of the 7970GE. Like its predecessors, Titan delivers the kind of awe-inspiring performance we have come to expect from NVIDIA’s most powerful video cards.
With that in mind, as our benchmark data has shown, Titan’s performance isn’t quite enough to unseat this generation’s multi-GPU cards like the GTX 690 or Radeon HD 7990. But with that said this isn’t a new situation for us, and we find our editorial stance has not changed: we still suggest single-GPU cards over multi-GPU cards when performance allows for it. Multi-GPU technology itself is a great way to improve performance beyond what a single GPU can do, but as it’s always beholden to the need for profiles and the inherent drawbacks of AFR rendering, we don’t believe it’s desirable in situations such as Titan versus the GTX 690. The GTX 690 may be faster, but Titan is going to deliver a more consistent experience, just not quite at the same framerates as the GTX 690.
Meanwhile in the world of GPGPU computing Titan stands alone. Unfortunately we’re not able to run a complete cross-platform comparison due to Titan’s outstanding OpenCL issue, but from what we have been able to run Titan is not only flat-out powerful, but NVIDIA has seemingly delivered on their compute efficiency goals, giving us a Kepler family part capable of getting far closer to its theoretical efficiency than GTX 680, and closer than any other GPU before it. We’ll of course be taking a further look at Titan in comparison to other GPUs once the OpenCL situation is resolved in order to come to a better understanding of its relative strengths and weaknesses, but for the first wave of Titan buyers I’m not sure that’s going to matter. If you’re doing GPU computing, are invested in CUDA, and need a fast compute card, then Titan is the compute card CUDA developers and researchers have been dreaming of.
Back in the land of consumer gaming though, we have to contend with the fact that unlike any big-GPU card before it, Titan is purposely removed from the price/performance curve. NVIDIA has long wanted to ape Intel’s ability to have an extreme/luxury product at the very top end of the consumer product stack, and with Titan they’re going ahead with that.
The end result is that Titan is targeted at a different demographic than GTX 580 or other such cards, a demographic that has the means and the desire to purchase such a product. Being used to seeing the best video cards go for less we won’t call this a great development for the competitive landscape, but ultimately this is far from the first luxury level computer part, so there’s not much else to say other than that this is a product for a limited audience. But what that limited audience is getting is nothing short of an amazing card.
Like the GTX 690, NVIDIA has once again set the gold standard for GPU construction, this time for a single-GPU card. GTX 680 was a well-built card, but next to Titan it suddenly looks outdated. For example, despite Titan’s significantly higher TDP it’s no louder than the GTX 680, and the GTX 680 was already a quiet card. Next to price/performance the most important metric is noise, and by focusing on build quality NVIDIA has unquestionably set the new standard for high-end, high-TDP video cards.
On a final note, normally I’m not one for video card gimmicks, but after having seen both of NVIDIA’s Titan concept systems I have to say NVIDIA has taken an interesting route in justifying the luxury status of Titan. With the Radeon HD 7970 GHz Edition only available with open air or exotic cooling, Titan has been put into a position where it’s the ultimate blower card by a wide margin. The end result is that in scenarios where blowers are preferred and/or required, such as SFF PCs or tri-SLI, Titan is even more of an improvement over the competition than it is for traditional desktop computers. Or as Anand has so eloquently put it with his look at Falcon Northwest’s Tiki, when it comes to Titan “The days of a high end gaming rig being obnoxiously loud are thankfully over.”
Wrapping things up, on Monday we’ll be taking a look at the final piece of the puzzle: Origin’s tri-SLI full tower Genesis PC. The Genesis has been an interesting beast for its use of water cooling with Titan, and with the Titan launch behind us we can now focus on what it takes to feed 3 Titan video cards and why it’s an impeccable machine for multi-monitor/surround gaming. So until then, stay tuned.

PCI\VEN_10DE&DEV_1005&SUBSYS_103510DEI have no idea what a Tesla card's would be, though.

I don't suppose you would know how to tell the computer/OS that the card has a different PCI DevID other than what it actually is, would you?NVIDIA Tesla C2075 PCI\VEN_10DE&DEV_1096

"This TDP limit is 106% of Titan’s base TDP of 250W, or 265W. No matter what you throw at Titan or how you cool it, it will not let itself pull more than 265W sustained."The value of the Titan isn't THAT bad at stock, but 106%? Is that a joke!?
Throw in an OC for OC comparison, and this card is absolutely ridiculous. Take the 7970 GE... 1250mhz is a good, reasonable 250mhz OC on air, a nice 20%-25% boost in performance.
The Titan review sample is probably the best case scenario and can go 27MHz past turbo speed, 115MHZ past base speed, so maybe 6%-10%. That $500 performance gap starts shrinking really, really fast once you OC, and for god sakes, if you're the kind of person who's buying a $1000 GPU, you shouldn't intend to leave it at stock speeds.
I hope someone can voltmod this card and actually make use of a waterblock, but there's another issue... Nvidia is obviously setting a precedent. Unless they change this OC policy, they won't be seeing any of my money anytime soon.

As someone with a 7970GE, I can tell you unequivocally that 1250MHz on air is not at all a given. My card can handle many games at 1150MMhz, but other titles and applications (say, running some compute stuff) and I'm lucky to get stability for more than a day at 1050MHz. Perhaps with enough effort playing with voltage mods and such I could improve the situation, but I'm happier living with a card for a couple years that doesn't crap out because of excessively high voltages.CeriseCogburn - Saturday, February 23, 2013 - link
" After a few hours of trial and error, we settled on a base of the boost curve of 9,80 MHz, resulting in a peak boost clock of a mighty 1,123MHz; a 12 per cent increase over the maximum boost clock of the card at stock.Despite the 3GB of GDDR5 fitted on the PCB's rear lacking any active cooling it too proved more than agreeable to a little tweaking and we soon had it running at 1,652MHz (6.6GHz effective), a healthy ten per cent increase over stock.
With these 12-10 per cent increases in clock speed our in-game performance responded accordingly."

Oh well, 12 is 6 if it's nVidia bash time, good job mr know it all.

YES! 1920x1080 has FINALLY arrived. It only took 6 years from when it became mainstream but it's FINALLY here! FINALLY! I get not doing it on this card, but can you guys PLEASE test graphics cards, especially laptop ones, at 1600x900 and 1280x720. A lot of the time when on a budget playing games at a lower resolution is a compromise you're more than willing to make in order to get decent quality settings. PLEASE do this for me, PLEASE!JarredWalton - Thursday, February 21, 2013 - link
Um... we've been testing 1366x768, 1600x900, and 1920x1080 as our graphics standards for laptops for a few years now. We don't do 1280x720 because virtually no laptops have that as their native resolution, and stretching 720p to 768p actually isn't a pleasant result (a 6.7% increase in resolution means the blurring is far more noticeable). For desktop cards, I don't see much point in testing most below 1080p -- who has a desktop not running at least 1080p native these days? The only reason for 720p or 900p on desktops is if your hardware is too old/slow, which is fine, but then you're probably not reading AnandTech for the latest news on GPU performance.colonelclaw - Thursday, February 21, 2013 - link
I must admit I'm a little bit confused by Titan. Reading this review gives me the impression it isn't a lot more than the annual update to the top-of-the-line GPU from Nvidia.What would be really useful to visualise would be a graph plotting the FPS rates of the 480, 580, 680 and Titan along with their release dates. From this I think we would get a better idea of whether or not it's a new stand out product, or merely this year's '780' being sold for over double the price.
Right now I genuinely don't know if i should be holding Nvidia in awe or calling them rip-off merchants.

From Anandtech's 7970 Review, you can see relative GPU die sizes:http://images.anandtech.com/doci/5261/DieSize.png
You'll also see the prices of these previous flagships has been mostly consistent, in the $500-650 range (except for a few outliers like the GTX 285 which came in hard economic times and the 8800Ultra, which was Nvidia's last ultra-premium card).
You an check some sites that use easy performance rating charts, like computerbase.de to get a quick idea of relative performance increases between generations, but you can quickly see that going from a new generation (not half-node) like G80 > GT200 > GF100 > GK100/110 should offer 50%+ increase, generally closer to the 80% range over the predecessor flagship.
Titan would probably come a bit closer to 100%, so it does outperform expectations (all of Kepler line did though), but it certainly does not justify the 2x increase in sticker price. Nvidia is trying to create a new Ultra-premium market without giving even a premium alternative. This all stems from the fact they're selling their mid-range part, GK104, as their flagship, which only occurred due to AMD's ridiculous pricing of the 7970.
