When NVIDIA launched their first consumer GK110 card back in February with the GeForce GTX Titan, one of the interesting (if frustrating) aspects of the launch was that we knew we wouldn’t be getting a “complete” GK110 card right away. GTX Titan was already chart-topping fast, easily clinching the crown for NVIDIA, but at the same time it was achieving those high marks with only 14 of GK110’s 15 SMXes active. The 15th SMX, though representing just 7% of GK110’s compute/geometry hardware, offered the promise of just a bit more performance out of GK110, and a promise that would have to wait to be fulfilled another day. For a number of reasons, NVIDIA would keep a little more performance in the tank in reserve for use in the future.

Jumping forward 8 months to the past few weeks, and things have significantly changed in the high-end video card market. With the launch of AMD’s new flagship video card, Radeon R9 290X, AMD has unveiled the means to once again compete with NVIDIA at the high end. And at the same time they have shown that they have the wherewithal to get into a fantastic, bloody price war for control of the high-end market. Right out of the gate 290X was fast enough to defeat GTX 780 and battle GTX Titan to a standstill, at a price hundreds of dollars cheaper than NVIDIA’s flagship card. The outcome of this has been price drops all around, with GTX 780 shedding $150, GTX Titan being all but relegated to the professional side of “prosumer,” and an unexpectedly powerful Radeon R9 290 practically starting the same process all over again just 2 weeks later.

With that in mind, NVIDIA has long become accustomed to controlling the high-end market and the single-GPU performance crown. AMD and NVIDIA may go back and forth at times, but at the end of the day it’s usually NVIDIA who comes out on top. So with AMD knocking at their door and eyeing what has been their crown, the time has come for NVIDIA to tap their reserve tank and to once again cement their hold. The time has come for GTX 780 Ti.

Getting right down to business, GeForce GTX 780 Ti unabashedly a response to AMD’s Radeon R9 290X while also serving as NVIDIA’s capstone product for the GeForce 700 series. With NVIDIA finally ready and willing to release fully enabled GK110 based cards – a process that started with Quadro K6000 – GTX 780 Ti is the obligatory and eventual GeForce part to bring that fully enabled GK110 GPU to the consumer market. By tapping the 15th and final SMX for a bit more performance and coupling it with a very slight clockspeed bump, NVIDIA has the means to fend off AMD’s recent advance while offering a refresh of their product line just in time for a busy holiday season and counter to the impending next-generation console launch.

Looking at the specifications for GTX 780 Ti in detail, at the hardware level GTX 780 Ti is the fully enabled GK110 GeForce part we’ve long been waiting for. Featuring all 15 SMXes up and running, GTX 780 Ti features 25% more compute/geometry/texturing hardware than the GTX 780 it essentially replaces, or around 7% more hardware than the increasingly orphaned GTX Titan. To that end the only place that GTX 780 Ti doesn’t improve on GTX Titan/780 is in the ROP department, as both of those cards already featured all 48 ROPs active, alongside the associated memory controllers and L2 cache.

Coupled with the fully enabled GK110 GPU, NVIDIA has given GTX 780 Ti a minor GPU clockspeed bump to make it not only the fastest GK110 card overall, but also the highest clocked card. The 875MHz core clock and 928MHz boost clock is only 15MHz and 28MHz faster than GTX 780 in their respective areas, but with GTX 780 already being clocked higher than GTX Titan, GTX 780 Ti doesn’t need much more in the way of GPU clockspeed to keep ahead of the competition and its older siblings. As a result if we’re comparing GTX 780 Ti to GTX 780, then GTX 780 relies largely on its SMX advantage to improve performance, combining a 1% clockspeed bump and a 25% increase in shader harder to offer 27% better shading/texturing/geometry performance and just 1% better ROP throughput than GTX 780. Or to compare things to Titan, then GTX 780 Ti relies on its more significant 5% clockspeed advantage coupled with its 7% functional unit increase to offer a 12% increase in shading/texturing/geometry performance, alongside a 5% increase in ROP throughput.

With specs and numbers in mind, there is one other trick up GTX 780 Ti’s sleeve to help push it past everything else, and that is a higher 7GHz memory clock. NVIDIA has given GK110 the 7GHz GDDR5 treatment with the GTX 780 Ti (making it the second card after GTX 770 to get this treatment), giving GTX 780 Ti 336GB/sec of memory bandwidth. This is 17% more than either GTX Titan or GTX 780, and even edging out the recently released Radeon R9 290X’s 320GB/sec. The additional memory bandwidth, though probably not absolutely necessary from what we’ve seen with GTX Titan, will help NVIDIA get as much out of GK110 as they can and further separate the card from other NVIDIA and AMD cards alike.

The only unfortunate news here when it comes to memory will be that unlike Titan, NVIDIA is sticking with 3GB for the default RAM amount on GTX 780 Ti. Though the performance ramifications of this will be minimal (at least at this time), will put the card in an odd spot of having less RAM than the cheaper Radeon R9 290 series.

Taken altogether then, GTX 780 Ti stands to be anywhere between 1% and 27% faster than GTX 780 depending on whether we’re looking at a ROP-bound or shader-bound scenario. Otherwise it stands to be between 5% and 17% faster than GTX Titan depending on whether we’re ROP-bound or memory bandwidth-bound.

Meanwhile let’s quickly talk about power consumption. As GTX 780 Ti is essentially just a spec bump of the GK110 hardware we’ve seen for the last 8 months, power consumption won’t officially be changing. NVIDIA designed GTX Titan and GTX 780 with the same power delivery system and the same TDP limit, with GTX 780 Ti further implementing the same system and the same limits. So officially GTX 780 Ti’s TDP stands at 250W just like the other GK110 cards. Though in practice power consumption for GTX 780 Ti will be higher than either of those other cards, as the additional performance it affords will mean that GTX 780 Ti will be on average closer to that 250W limit than either of those cards.

Finally, let’s talk about pricing, availability, and competitive positioning. On a pure performance basis NVIDIA expects GTX 780 Ti to be the fastest single-GPU video card on the market, and our numbers back them up on this. Consequently NVIDIA is going to be pricing and positioning GTX 780 Ti a lot like GTX Titan/780 before it, which is to say that it’s going to be priced as a flagship card rather than a competitive card. Realistically AMD can’t significantly threaten GTX 780 Ti, and although it’s not going to be quite the lead that NVIDIA enjoyed over AMD earlier this year, it’s enough of a lead that NVIDIA can pretty much price GTX 780 Ti based solely on the fact that it’s the fastest thing out there. And that’s exactly what NVIDIA has done.

To that end GTX 780 Ti will be launching at $699, $300 less than GTX Titan but $50 higher than the original GTX 780’s launch price. By current prices this will put it $150 over the R9 290X or $200 over the reprised GTX 780, a significant step over each. GTX 780 Ti will have the performance to justify its positioning, but just as the previous GK110 cards it’s going to be an expensive product. Meanwhile GTX Titan will be remaining at $999, despite the fact that it’s now officially dethroned as the fastest GeForce card (GTX 780 having already made it largely redundant). At this point it will live on as NVIDIA’s entry level professional compute card, keeping its unique FP64 performance advantage over the other GeForce cards.

Elsewhere on a competitive basis, until such a time where factory overclocked 290X cards hit the market, the only real single-card competition for GTX 780 Ti will be the Radeon HD 7990, AMD’s Tahiti based dual-GPU card, which these days retails for close to $800. Otherwise the closest competition will be dual card setups, such as the GTX 770 SLI, R9 280X CF, and R9 290 CF. All of those should present formidable challenges on a pure performance basis, though it will bring with it the usual drawbacks of multi-GPU rendering.

Meanwhile, as an added perk NVIDIA will be extending their recently announced “The Way It’s Meant to Be Played Holiday Bundle with SHIELD” promotion to the GTX 780 Ti, which consists of Assassins’ Creed IV, Batman: Arkham Origins, Splinter Cell: Blacklist, and a $100 SHIELD discount. NVIDIA has been inconsistent about this in the past, so it’s a nice change to see it included with their top card. As always, the value of bundles are ultimately up to the buyer, but for those who do place value in the bundle it should offset some of the sting of the $699 price tag.

Finally, for launch availability this will be a hard launch. Reference cards should be available by the time this article goes live, or shortly thereafter. It is a reference launch, and while custom cards are in the works NVIDIA is telling us they likely won’t hit the shelves until December.

    Sure, you can save money by buying into the R9 290X, but save that money because you're going to need it in a few years for a hearing aid. Reply

    As if there won't be any custom-cooled R290X-based GPUs. You make it sound like all GPU vendors and partners have abandoned AMD, and that AMD is going to be stuck with that fan forever. Well done for being short-sighted. Reply

    Personally I find it Kinda sad given the Fact that GK110 is a much bigger chip in general it would have a bigger lead at stock. Plus powerusage while gaming goes back and forth with the titan, it is competing with. Nvidia just has more aggressive TDP throttling, while AMD's is mainly temp based.

    290x is only hot under stock cooler, It actually runs pretty cool under water. Also 290x is doing more with less transistors compared to Nvidia. Sucks Nvidia needs to scale Kepler to such a higer level just to compete with AMD's lower offerings. AMD would slaughter Nvidia with a Die of equal size.

    Also with the 290 being $399 Nvidia is boned, unless the drop the gtx780's price again. 290 @ 1300mhz is about the same as a 780 @ 1400mhz.

    G-Sync only works with one monitor so far, and considering I already have a 120hz monitor and already get a taste of wants to come I could care less. We won't see it in anything not overpriced for years to come, by that time we will probably have a open standard that both Intel and AMD can use. Plus I want a 1440p ISP with G-Sync and doubt that will happen any time soon. Mantle is by far a more interesting option if you ask me. I already with with vsync off and get no tearing and games are as smooth as ever with AMD's current drivers. Smoother then my old Nvidia card, though I just made the switch to AMD and never really had the chance to use the old "crap" drivers.

    The problem with this card is the 25% price premium over AMD's 290X for 11% more performance.

    The only real advantage it has over the 290X is lower noise. Other than that it lacks next-gen optimizations (Mantel, EA partnership, console ports, etc.)

    erm... 290x in uber mode is edged by what? 1-5%... I can't call this a win + GK110 has reached it's full potential. And 780Ti is basically an excelent GK110 chip castrated and sold for 700$ instead of the regular 4k$ (K6000) + they pushed GDDR5 to it's maximum to just edge the 290x... I don't know... This thing looks like vapor ware, let's see some availability but I doubt it's ok for nvidia to sell a perfectly good chip for what? 6 times less? Plus the last tests with 290 without the x show that 290x has lots of potential left

    How I see it 290x was rushed to market and suffers because of it bad cooler, high temperatures and slow memory... 780ti is the best of the Kepler architecture Oc'ed both memory & gpu with basically a pro grade chip and 30% more diespace and it just barelly edges out the 290x in uber mode.

    What AMD managed is to make nvidia divert perfect GK110's from pro line to mainstream and shifted their focus - which is a bad thing to do atm for nvidia. And nvidia reacted like a... fanboy really by scrambling to bring a lab rat on the market... just to barely claim the crown back... instead of focusing on maxwell and pro line improvements... They really behaved like little kids with ADHD with this one... but ... oh well...
