Never 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.

    Correct, but then they should have priced it around $800, not $1k. The reason they could demand $1k for the original Titan was due to the FP64 compute functionality on board.

    This is exactly what they did when they made the GTX 560 Ti, chopped out the compute features to maximize gaming power at a low cost. The reason that one was such a great card was due to price positioning, not just performance.
  • chizow - Monday, March 23, 2015 - link

    @Denithor, I disagree, the reason they could charge $1K for the original Titan was because there was still considerable doubt there would ever be a traditionally priced GeForce GTX card based on GK110, the compute aspect was just add-on BS to fluff up the price.

    Since then of course, they released not 1, but 2 traditional GTX cards (780 and Ti) that were much better received by the gaming market in terms of both price and in the case of the Ti, performance. Most notably was the fact the original Titan price on FS/FT and Ebay markets quickly dropped below that of the 780Ti. If the allure of the Titan was indeed for DP compute, it would have held its price, but the fact Titan owners were dumping their cards for less than what it cost to buy a 780Ti clearly showed the demand and price justification for a Titan for compute alone simply wasn't there. Also, important to note Titan's drivers were still GeForce, so even if it did have better DP performance, there were still a lot of driver limitations related to CUDA preventing it from reaching Quadro/Tesla levels of performance.

    Simply put, Nvidia couldn't pull that trick again under the guise of compute this time around, and people like me who weren't willing to pay a penny for compute over gaming weren't willing to justify that price tag for features we had no use for. Titan X on the other hand, its 100% dedicated to gamers, not a single transistor budgeted for something I don't care about, and no false pretenses to go with it.

    The identity crisis this card has with itself is that for all the effort, it's still slower than two 980's in SLI, and when overclocked to try to catch up to them, ends up using MORE POWER than two 980's in SLI.

    So for the price (being identical) wouldn't you just pick up two 980's which offer more performance, less power consumption and FP64 (even if you don't need it, it'll help the resell value in the future)?
  • LukaP - Thursday, March 19, 2015 - link

    The 980 have the same 1/32 DP performance as the Titan X. And Titan never was a sensible card. Noone sensible buys it over a x80 of that generation (which i assume will be 1080 or whatever they call it, based on GM200 with less ram, and maybe some disabled ROPs).

    The Titan is a true flagship. making no sense economically, but increasing your penis size by miles
  • chizow - Monday, March 23, 2015 - link

    I considered going this route but ultimately decided against it despite having used many SLI setups in the past. There's a number of things to like about the 980 but ultimately I felt I didn't want to be hamstrung by the 4GB in the future. There are already a number of games that push right up to that 4GB VRAM usage at 1440p and in the end I was more interested in bringing up min FPS than absolutely maxing out top-end FPS with 980 SLI.

    Power I would say is about the same, 980 is super efficient but once overclocked, with 2 of them I am sure the 980 set-up would use as much if not more than the single Titan X.
  • naxeem - Saturday, March 21, 2015 - link

    You're forgetting three things:

    1. NO game uses even close to 8GB, let alone 12

    2. $1000/1300€ puts it to exactly double the price of exactly the same performance level you get with any other solution: 970 SLI kicks it with $750, 295x2 does the same, 2x290X also...
    In Europe, the card is even 30% more expensive than in US and than other cards so even less people will buy it there.

    3. In summer, when AMD releases 390X for $700 and gives even better performance, Nvidia will either have to drop TitanX to the same price or suffer being smashed around at the market.

    Keep in mind HBM is seriously a performance kicker for high resolutions, end-game gaming that TitanX is intended for. No amount of RAM can counter RAM bandwidth, especially when you don't really need over 6-7GB for even the most demanding games out there.
  • ArmedandDangerous - Saturday, March 21, 2015 - link

    Or they could just say fuck it and keep the Titan at it's exact price and release a x80 GM200 at a lower price with some features cut that will still compete with whatever AMD has to offer. This is the 3rd Titan, how can you not know this by now.
  • naxeem - Tuesday, March 24, 2015 - link

    Well, yes. But without any compute performance of previous Titans, who would any why buy a 1000 Titan X while having exact same performance in some 980Ti or alike?
    Those who need 12GB for rendering may as well buy Quadros with more VRAM... When you need 12, you need more anyway... For gaming, 12GB means jack sht.
  • Thetrav55 - Friday, March 20, 2015 - link

    Well its only the fastest card in the WORLD look at it that way the fattest card in the world ONLY 1000$ I know I know 1000 does not justify the performance but its the fastest card in the WORLD!!!
  • agentbb007 - Wednesday, June 24, 2015 - link

    LOL had to laugh @ farealstarfareal's comment that the 390X would likely blow the doors off the Titan X, the 390X is nowhere near the Titan X, it's closer to a 980. The all mighty R9 FuryX reviews posted this morning and it's not even beating the 980ti.
