The NVIDIA GeForce GTX Titan X Review
by Ryan Smith on March 17, 2015 3:00 PM ESTNever one to shy away from high-end video cards, in 2013 NVIDIA took the next step towards establishing a definitive brand for high-end cards with the launch of the GeForce GTX Titan. Proudly named after NVIDIA’s first massive supercomputer win – the Oak Ridge National Laboratory Titan – it set a new bar in performance. It also set a new bar in build quality for a single-GPU card, and at $999 it also set a new bar in price. The first true “luxury” video card, NVIDIA would gladly sell you one of their finest video cards if you had the pockets deep enough for it.
Since 2013 the Titan name has stuck around for additional products, although it never had quite the same impact as the original. The GTX Titan Black was a minor refresh of the GTX Titan, moving to a fully enabled GK110B GPU and from a consumer/gamer standpoint somewhat redundant due to the existence of the nearly-identical GTX 780 Ti. Meanwhile the dual-GPU GTX Titan Z was largely ignored, its performance sidelined by its unprecedented $3000 price tag and AMD’s very impressive Radeon R9 295X2 at half the price.
Now in 2015 NVIDIA is back with another Titan, and this time they are looking to recapture a lot of the magic of the original Titan. First teased back at GDC 2015 in an Epic Unreal Engine session, and used to drive more than a couple of demos at the show, the GTX Titan X gives NVIDIA’s flagship video card line the Maxwell treatment, bringing with it all of the new features and sizable performance gains that we saw from Maxwell last year with the GTX 980. To be sure, this isn’t a reprise of the original Titan – there are some important differences that make the new Titan not the same kind of prosumer card the original was – but from a performance standpoint NVIDIA is looking to make the GTX Titan X as memorable as the original. Which is to say that it’s by far the fastest single-GPU card on the market once again.

To do this NVIDIA has assembled a new Maxwell GPU, GM200 (aka Big Maxwell). We’ll dive into GM200 in detail a bit later, but from a high-level standpoint GM200 is the GM204 taken to its logical extreme. It’s bigger, faster, and yes, more power hungry than GM204 before it. In fact at 8 billion transistors occupying 601mm2 it’s NVIDIA’s largest GPU ever. And for the first time in quite some time, virtually every last millimeter is dedicated to graphics performance, which coupled with Maxwell’s performance efficiency makes it a formidable foe.
Diving into the specs, GM200 can for most intents and purposes be considered a GM204 + 50%. It has 50% more CUDA cores, 50% more memory bandwidth, 50% more ROPs, and almost 50% more die size. Packing a fully enabled version of GM200, this gives the GTX Titan X 3072 CUDA cores and 192 texture units(spread over 24 SMMs), paired with 96 ROPs. Meanwhile considering that even the GM204-backed GTX 980 could outperform the GK110-backed GTX Titans and GTX 780 Ti thanks to Maxwell’s architectural improvements – 1 Maxwell CUDA core is quite a bit more capable than Kepler in practice, as we’ve seen – GTX Titan X is well geared to shoot well past the previous Titans and the GTX 980.
Feeding GM200 is a 384-bit memory bus driving 12GB of GDDR5 clocked at 7GHz. Compared to the GTX Titan Black this is one of the few areas where GTX Titan X doesn’t have an advantage in raw specifications – there’s really nowhere to go until HBM is ready – however in this case numbers can be deceptive as NVIDIA has heavily invested in memory compression for Maxwell to get more out of the 336GB/sec of memory bandwidth they have available. The 12GB of VRAM on the other hand continues NVIDIA’s trend of equipping Titan cards with as much VRAM as they can handle, and should ensure that the GTX Titan X has VRAM to spare for years to come. Meanwhile sitting between the GPU’s functional units and the memory bus is a relatively massive 3MB of L2 cache, retaining the same 32K:1 cache:ROP ratio of Maxwell 2 and giving the GPU more cache than ever before to try to keep memory operations off of the memory bus.
As for clockspeeds, as with the rest of the Maxwell lineup GTX Titan X is getting a solid clockspeed bump from its Kepler predecessor. The base clockspeed is up to 1Ghz (reported as 1002MHz by NVIDIA’s tools) while the boost clock is 1075MHz. This is roughly 100MHz (~10%) ahead of the GTX Titan Black and will further push the GTX Titan X ahead. However as is common with larger GPUs, NVIDIA has backed off on clockspeeds a bit compared to the smaller GM204, so GTX Titan X won’t clock quite as high as GTX 980 and the overall performance difference on paper is closer to 33% when comparing boost clocks.
Power consumption on the other hand is right where we’d expect it to be for a Titan class card. NVIDIA’s official TDP for GTX Titan X is 250W, the same as the previous single-GPU Titan cards (and other consumer GK110 cards). Like the original GTX Titan, expect GTX Titan X to spend a fair bit of its time TDP-bound; 250W is generous – a 51% increase over GTX 980 – but then again so is the number of transistors that need to be driven. Overall this puts GTX Titan X on the high side of the power consumption curve (just like GTX Titan before it), but it’s the price for that level of performance. Practically speaking 250W is something of a sweet spot for NVIDIA, as they know how to efficiently dissipate that much heat and it ensures GTX Titan X is a drop-in replacement for GTX Titan/780 in any existing system designs.
Moving on, the competitive landscape right now will greatly favor NVIDIA. With AMD’s high-end having last been refreshed in 2013 and with the GM204 GTX 980 already ahead of the Radeon 290X, GTX Titan X further builds on NVIDIA’s lead. No other single-GPU card is able to touch it, and even GTX 980 is left in the dust. This leaves NVIDIA as the uncontested custodian of the single-GPU performance crown.
The only thing that can really threaten the GTX Titan X at this time are multi-GPU configurations such as GTX 980 SLI and the Radeon R9 295X2, the latter of which is down to ~$699 these days and is certainly a potential spoiler for GTX Titan X. To be sure when multi-GPU works right either of these configurations can shoot past a single GTX Titan X, however when multi-GPU scaling falls apart then we have the usual problem of such setups falling well behind a single powerful GPU. Such setups are always a risk in that regard, and consequently as a single-GPU card GTX Titan X offers the best bet for consistent performance.
NVIDIA of course is well aware of this, and with GTX 980 already fending off the R9 290X NVIDIA is free to price GTX Titan X as they please. GTX Titan X is being positioned as a luxury video card (like the original GTX Titan) and NVIDIA is none too ashamed to price it accordingly. Complicating matters slightly however is the fact that unlike the Kepler Titan cards the GTX Titan X is not a prosumer-level compute monster. As we’ll see it lacks its predecessor’s awesome double precision performance, so NVIDIA does need to treat this latest Titan as a consumer gaming card rather than a gaming + entry level compute card as was the case with the original GTX Titan.
In any case, with the previous GTX Titan and GTX Titan Black launching at $999, it should come as no surprise that this is where GTX Titan X is launching as well. NVIDIA saw quite a bit of success with the original GTX Titan at this price, and with GTX Titan X they are shooting for the same luxury market once again. Consequently GTX Titan X will be the fastest single-GPU card you can buy, but it will once again cost quite a bit to get. For our part we'd like to see GTX Titan X priced lower - say closer to the $700 price tag of GTX 780 Ti - but it's hard to argue with NVIDIA's success on the original GTX Titan.
Finally, for launch availability this will be a hard launch with a slight twist. Rather than starting with retail and etail partners such as Newegg, NVIDIA is going to kick things off by selling cards directly, while partners will start to sell cards in a few weeks. For a card like GTX Titan X, NVIDIA selling cards directly is not a huge stretch; with all cards being identical reference cards, partners largely serve as distributors and technical support for buyers.
Meanwhile selling GTX Titan X directly also allowed NVIDIA to keep the card under wraps for longer while still offering a hard launch, as it left fewer avenues for leaks through partners. On the other hand I'm curious how partners will respond to being cut out of the loop like this, even if it is just temporary.

The titan was teased 10 days ago...Tunnah - Wednesday, March 18, 2015 - link
It feels nVidia are just taking the pee out of us now. I was semi-miffed at the 970 controversy, I know for business reasons etc. it doesn't make sense to truly trounce the competition (and your own products) when you can instead hold something back and keep it tighter, and have something to release in case they surprise you.And I was semi-miffed when I heard it would be more like a 33% improvement over the current cream of the crop, instead of the closer to 50% increase the Titan was over the 680, because they have to worry about the 390x, and leave room for a Titan X White Y Grey SuperHappyTime version.
But to still charge $1000 even though they are keeping the DP performance low, this is just too far. The whole reasoning for the high price tag was you were getting a card that was not only a beast of a gaming card, but it would hold its own as a workstation card too, as long as you didn't need the full Quadro service. Now it is nothing more than a high end card, a halo product...that isn't actually that good!
When it comes down to it, you're paying 250% the cost for 33% more performance, and that is disgusting. Don't even bring RAM into it, it's not only super cheap and in no way a justification for the cost, but in fact is useless, because NO GAMER WILL EVER NEED THAT MUCH, IT WAS THE FLIM FLAMMING WORKSTATION CROWD WHO NEEDING THAT FLIM FLAMMING AMOUNT OF FLOOMING RAM YOU FLUPPERS!
This feels like a big juicy gob of spit in our faces. I know most people bought these purely for the gaming option and didn't use the DP capability, but that's not the point - it was WORTH the $999 price tag. This simply is not, not in the slightest. $650, $750 tops because it's the best, after all..but $999 ? Not in this lifetime.
I've not had an AMD card since way back in the days of ATi, I am well and truly part of the nVidia crowd, even when they had a better card I'd wait for the green team reply. But this is actually insulting to consumers.
I was never gonna buy one of these, I was waiting on the 980Ti for the 384bit bus and the bumps that come along with it...but now I'm not only hoping the 390x is better than people say because then nVidia will have to make it extra good..I'm hoping it's better than they say so I can actually buy it.
For shame nVidia, what you're doing with this card is unforgivable

So you`re blaming a for-profit company for being for-profit.maximumGPU - Wednesday, March 18, 2015 - link
no he's not. He's blaming a for-profit compaby abusing it's position at the expense of its customers.Maxwell is great, and i've got 2 of them in my rig. But titan X is a bit of a joke. The only justification the previous titan had was that it could be viewed as a cheap professional cards. Now that's gone but you're still paying the same price.
Unfortunately nvidia will put the highest price they can get away with, and 999$ doesn't seem to deter some hardcore fans no matter how much poor value it represents.
I certainly hope the sales don't meet their expectations.

I would argue that the vram may be needed later on. 4GB is already tight with SoM, and future games will only push that up.people said that 6GB was too much for the OG titan, but SoM can eat that up at 4k, and other games are not far behind. especially for SLI setups, that memory will come in handy.
Thats what really killed the 770. gpu was fine for me, but 2GB was way to little vram.

Not being a gamer, I would like to see a review in which many of these top-of-the-line gaming cards are tested against a different sort of environment. For example, I'd love to see how cards compare handling graphics software packages such as Photoshop, Premier Pro, Lightwave, Cinema 4D, SolidWorks and others. If these cards are really pushing the envelope, then they should compare against the Quadro and FirePro lines.Ranger101 - Wednesday, March 18, 2015 - link
I think it's safe to say that Nvidia make technically superior cards as compared to AMD,at least as far as the last 2 generations of GPUs are concerned. While the AMD cards consume
more power and produce more heat, this issue is not a determining factor when I upgrade unlike
price and choice.
I will not buy this card, despite the fact that I find it to be a very desirable and
techically impressive card, because I don't like being price-raped and because
I want AMD to be competitive.
I will buy the 390X because I prefer a "consumer wins" situation where there are at least 2
companies producing competitive products and lets be clear AMD GPUs are competitve, even when you factor in what is ultimately a small increase in heat and noise, not to mention lower prices.
It was a pleasant surprise to see the R295X2 at one point described as "very impressive" yet
I think it would have been fair if Ryan had drawn more attention to AMD "wins," even though they
are not particularly significant, such as the most stressful Shadow of Mordor benchmarks.
Most people favour a particular brand, but surely even the most ardent supporters wouldn't want to see a situation where there is ONLY Intel and ONLY Nvidia. We are reaping the rewards of this scenario already in terms of successive generations of Intel CPUs offering performance improvements that are mediocre at best.
I can only hope that the 390X gets a positive review at Anandtech.

Looking forward to a 390 with the same performance for 400-500. I certainly got my money's worth out of the r9 290 when it was released. Don't understand how anyone could advocate this $1000 single card price bracket created for "top tier".Geforce man - Wednesday, March 18, 2015 - link
What still frustrates me, is the lack of using a modern aftermarket r9 290/x.Crunchy005 - Wednesday, March 18, 2015 - link
I actually really like how the new titan looks, shows what can be done. The problem with this card at this price point is it defeats what the titan really should be. Without the couple precision performance this card becomes irrelevant I feel(overpriced gaming card). The original titan was an entry level compute card outside of the quadro lineup. I know there are drawbacks to multiGPU setups but I would go for 2 980's or 970's for same or less money than the Titan X.I also found these benchmarks very interesting because you can see how much each game can be biased to a certain card. AMDs 290x, an old card, beat out the 980 in some cases, mostly at 4k resolutions and lost in others at the same resolution. Just goes to show that you also have to look at individual game performance as well as overall performance when buying a card.
Can't wait for the 390x from AMD that should be very interesting.
