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.

"Titan delivers the kind of awe-inspiring performance we have come to expect from NVIDIA’s most powerful video cards."If you hear unfiltered Nvidia marketing speak like this, you know that AT isn't fooling around when it comes to earning their PR dollars. Well done!

Paper launch? Fine. I get that. But I suspect stock levels will be seriously limited. Rumour has it that only 10,000 of these will be made - which seems very odd as even with a substantial profit marging - the ROI on development costs is going to be hard to recoup with a potential sales level as low as that.I'm looking to buy a couple of these as soon as they are available for SLI - maybe 3 for a triple set up if possible, but I can see there being real issues with stock. I decent solution 3 screen at 2560x1440 for sure - if you can get hold of them anywhere.

Note that NVIDIA specifically shot down the 10K card rumor. As far as we've been advised and as best as we can tell, card availability will be similar to what we saw with the GTX 690. Which is to say tight at first, but generally available and will continue to be available.Egg - Thursday, February 21, 2013 - link
The chart on page 1 is missing a 'GB' under GTX Titan's VRAM listing. There aren't any 5760*1200 non-GE 7970 benchmarks. Also, on the Power, Temperature, and Noise page, "temperate" should be "temperature" just before the first chart.Additionally, the voltage issue HollyDOL and the strange Crysis Warhead 1080p E Shader/G Quality issue silverblue mentioned should be clarified as well. (I'm just repeating them here so they have a higher chance of being seen.)
Also, Wolfram|Alpha interprets "gigaflops" as "billion floating point operations per second" by default, while offering an alternative interpretation that doesn't have the seconds unit. Wikipedia also defines flops as already having the time unit. By their standards, flops/s is technically incorrect. I'm not scientist, and I actually didn't notice this until typed gigaflops into Wolfram|Alpha, so take this for what little it's worth.
It's silly to suggest that this card needs a voltmod and a waterblock. Very few people doing scientific work are going to be having time to do that. This card isn't intended to be a gaming card. Yes, there undoubtedly will be people on hwbot who would love to do such a thing, but relative to the population of scientists living on meager grants, they're small.
It's also silly to say that Titan is a bad card because it isn't as efficient as other cards at password hashing or bitcoin mining. These embarallel workloads aren't representative of scientific workloads. Besides, the most dedicated people have a custom FPGAs or ASICs for those workloads.
Saying that it shows Nvidia jacking up prices on its flagship is misleading. Yes, it's technically true. But I saw someone say that the GTX 680 was only a "midrange" card. The GTX 680 still competes with the Radeon 7970 GE. It isn't outright winning anymore - in certain games, it loses - and it's often substantially more expensive. But it's still reasonably competitive. Why did anyone expect Titan to push down GTX 680 prices? If anything, it might push down Tesla 20X prices, but I'm not holding my breath.
Would anyone have complained about Nvidia being outrageously greedy if Titan didn't exist in the consumer space at all?
(Moreover, the GTX 580 had FP64 performance at 1/8 FP32 performance, not Titan's 1/3. (http://www.anandtech.com/show/4008/nvidias-geforce...
Simply looking at the specs partially explains why the card is so damn expensive. It's 7.1 billion transistors, compared to the GTX 690's 2*3.5 billion transistors. (Page 1 on this article). Going purely by transistor count, Titan is underpriced, because it's just as expensive as the GTX 690. Looking at die area instead is less forgiving, but don't forget that squeezing 7 billion transistors on a single die is more difficult than having two 3.5 billion transistor dies. Titan also has 2 extra gigabytes of GDDR5.
The only valid criticism I've seen is that Titan can be outperformed by two 7970 GEs in certain, mostly FP32 compute workloads, which are a cheaper solution, especially for scientists who probably aren't as concerned with heat production as those working on the Titan supercomputer. After all, you can fit bigger fans in an EATX case than in most racks. 689 Gflops is still greater than 50% of 1309 Gflops; it's 53%. When you can find the cheapest 7970 GEs at a bit over $400, two 7970s will be about $200 cheaper.
But figure in power: http://www.wolframalpha.com/input/?i=200+W+*+1+yea... . After a year of continuous usage (or two years of 50% utilization), and assuming that two 7970 GEs will use 200 more watts than a Titan - a fairly reasonable estimate in my opinion - Wolfram|Alpha informs us that we'll have saved $216.
Not to mention the fact that two 7970s occupy around twice as much space as a Titan. That means you need more individual systems if you're looking to scale beyond a single workstation.
And finally, anyone who needs as much memory per GPU as they can get will need Titan.
It's hard to draw any real conclusions right now, though, with DirectCompute dubious and OpenCL broken. Great work on Nvidia's part, getting the drivers working...
There's also the fact that Nvidia is marketing this as a gaming card, which is disingenuous and poor practice. But come on, we all read Anandtech for a reason. Overhyped marketing is nothing new in technology.
So in conclusion - treat the GTX 680 as the flagship single-GPU consumer card. (They did call it a 680. See the GTX 580, 480, and 280.) It's in roughly in 7970GE's ballpark when it comes to price and performance. For gamers, Titan can effectively be ignored.
If you need FP32 compute performance, consider multiple 7970 GEs as well as Titan.
If you need FP64 compute performance, Titan is unparalleled, assuming you run it for a decent amount of time.
And if you're trying to set a world record, well, I guess you can pay through the nose for Titan too.

Thank you, so many here just sound like butt hurt kids that do not understand these concepts or maybe didn't even read the article. Few of them would buy it at the $700 they cry about wanting it to be.This card is not just for gamers, and even if it were, performance wise it crushes the next closest single GPU competitor. Remember when Intel EE editions were $1k? The best always costs extra... and in this case the card isn't even being marketed soley for gamers anyway.
Until AMD puts out a new card that can beat it for cheaper, this will remain a $1k. Until then, the 680, 670, and 660 are all competitive products.

Don't expect the crybaby fools to respond. They'd prefer to pretend your post isn't here.If they do say anything, it will just be another repetitious pile of tinfoil hat lies Charlie D will be proud of.

Still only average framerates? :(I had hoped you'd move to minimum framerate / max frametime based benchmarking. Averages are (and were) kinda meaningless.

Actually we have some FRAPS data for a few of our games as a trial of some ideas. Unfortunately you won't see it for this article as there simply wasn't enough time to put that together on top of everything else. But keep your eyes peeled.GiantPandaMan - Thursday, February 21, 2013 - link
The Titan was a compute part, first and foremost. Gamers have much better alternatives in the 7970/680 route.Personally I think it's a pretty impressive piece of hardware, though there's no way in hell I'd ever buy it. That's because I'm a value oriented buyer and I don't have that much disposable income.
I just don't get all the indignation and outrage. It's not like nVidia screwed you over in some way. They had an expensive piece of hardware designed for compute and said to themselves, what the hell, why not release it for gamers?
