The NVIDIA GeForce GTX 780 Ti Review
by Ryan Smith on November 7, 2013 9:01 AM ESTMeet The GeForce GTX 780 Ti
When it comes to the physical design and functionality of the GTX 780 Ti, to no surprise NVIDIA is sticking with what works. The design of the GTX Titan and its associated cooler have proven themselves twice over now between the GTX Titan and the GTX 780, so with only the slightest of changes this is what NVIDIA is going with for GTX 780 Ti, too. Consequently there’s very little new material to cover here, but we’ll quickly hit the high points before recapping the general design of what has now become the GTX 780 series.
The biggest change here is that GTX 780 Ti is the first NVIDIA launch product to feature the new B1 revision of their GK110 GPU. B1 has already been shipping for a couple of months now, so GTX 780 Ti isn’t the first card to get this new GPU. However while GTX Titan and GTX 780 products currently contain a mix of the old and new revisions as NVIDIA completes the change-over, GTX 780 Ti will be B1 (and only B1) right out the door.
As for what’s new for B1, NVIDIA is telling us that it’s a fairly tame revision of GK110. NVIDIA hasn’t made any significant changes to the GPU, rather they’ve merely gone in and fixed some errata that were in the earlier revision of GK110, and in the meantime tightened up the design and leakage just a bit to nudge power usage down, the latter of which is helpful for countering the greater power draw from lighting up the 15th and final SMX. Otherwise B1 doesn’t have any feature changes nor significant changes in its power characteristics relative to the previous revision, so it should be a fairly small footnote compared to GTX 780.
The other notable change coming with GTX 780 Ti is that NVIDIA has slightly adjusted the default temperature throttle point, increasing it from 80C to 83C. The difference in cooling efficiency itself will be trivial, but since NVIDIA is using the exact same fan curve on the GTX 780 Ti as they did the GTX 780, the higher temperature throttle effectively increases the card’s equilibrium point, and therefore the average fan speed under load. Or put another way, but letting it get a bit warmer the GTX 780 Ti will ramp up its fan a bit more and throttle a bit less, which should help offset the card’s increased power consumption while also keeping thermal throttling minimized.

Moving on, since the design of the GTX 780 Ti is a near carbon copy of GTX 780, we’re essentially looking at GTX 780 with better specs and new trimmings. NVIDIA’s very effective (and still quite unique) metallic GTX Titan cooler is back, this time featuring black lettering and a black tinted window. As such GTX 780 Ti remains a 10.5” long card composed of a cast aluminum housing, a nickel-tipped heatsink, an aluminum baseplate, and a vapor chamber providing heat transfer between the GPU and the heatsink. The end result is the GTX 780 Ti is a quiet card despite the fact that it’s a 250W blower design, while still maintaining the solid feel and eye-catching design that NVIDIA has opted for with this generation of cards.
Drilling down, the PCB is also a re-use from GTX 780. It’s the same GK110 GPU mounted on the same PCB with the same 6+2 phase power design. This being despite the fact that GTX 780 Ti features faster 7GHz memory, indicating that NVIDIA was able to hit their higher memory speed targets without making any obvious changes to the PCB or memory trace layouts. Meanwhile the reuse of the power delivery subsystem is a reflection of the fact that GTX 780 Ti has the same 250W TDP limit as GTX 780 and GTX Titan, though unlike those two cards GTX 780 Ti will have the least headroom to spare and will come the closest to hitting it, due to the general uptick in power requirements from having 15 active SMXes. Finally, using the same PCB also means that GTX 780 has the same 6pin + 8pin power requirement and the same display I/O configuration of 2x DL-DVI, 1x HDMI, 1x DisplayPort 1.2.
On a final note, for custom cards NVIDIA won’t be allowing custom cards right off the bat – everything today will be a reference card – but with NVIDIA’s partners having already put together their custom GK110 designs for GTX 780, custom designs for GTX 780 Ti will come very quickly. Consequently, expect most (if not all of them) to be variants of their existing custom GTX 780 designs.

They live in a dream world. Pros buy Nvidia 80% plus. That says everything about quality and reliability.Mondozai - Friday, December 13, 2013 - link
EJS, the buttboy for Nvidia, most sane people are non-fanboys.This means most people, including myself, skipped AMD the last few generations because they did a shitty job. We bought Nvidia hardware instead. Now, the roles will be changed with aftermarket coolers.
Also, please don't talk about mouthbreathers when you're literally chewing cowshit in your mouth everytime you're trying to say something. It stinks.

You really don't know what you are talking about. Obviously, R9 290 holds great price/performance value but GTX 780 Ti has great OC potential out of the box. I'm afraid AMD shot themselves on their own foot with this reference coolerGrugtuck - Friday, November 8, 2013 - link
Any reason why the 900000000 pound gorilla in the room isnt mentioned here? 290x spanks the living **** out of the 780i in CF vs SLI. It makes me think that driver issues are still not fully sorted out.Ryan you sound like an absolute idiot when you say that no one is going to need SLI or CF any more. I also think its interesting how these days suddenly 60FPS is the standard to live by when it comes to FPS. I started playing PC games competitively back around 2002 and 80FPS has always been what people shot for, not 60. 60 is the bar min for acceptable smooth play, its not the optimal for competitive or serious FPShooter gaming.

Hmmm I figured I would run a quick bench... my OCed 780 gigabyte with stock cooling gets the same average fps as their OCed 780ti in metro... 67fps 1440p high preset.I imagine it would be even higher if I uninstall comodo (which seems to drop my average fps by 5-14 frames just by being installed even if everything is disabled and profiles are set up correctly to ignore games, goes right back up if uninstalled though)
I hit 77degrees after my third run and it dropped back down to 75 soon after when the fans ramped up again, keeping in mind this is Western Australia I am in currently at 34 degrees (that is 94.2 Fahrenheit), all the windows open and no air-conditioning with an aircooled case.
It isn't even a demanding overclock +161 to core and +189 to memory... which considering I usually run it at +181 and +201 with ease and stability (I turned it down to see what the results were for an easy overclock as they didn't push their 780ti much)
I was feeling like crap about them releasing a new card just 4=5months after I got the 780... now... not so

I think obviously people are just irate with Nvidia thinking they can charge premiums on everything and not just small premiums but they seem really set on this +750$ area pricing refusing to cut their customer base a break on the overpricing.So they drop down the 780 GTX to 500$ and everyone cheers "ignorantly" !!! Really its just a smoke screen because they knew the 290 and 290x were out performing their card while running on poor performing cooling units and yet it still has a $100 premium over the 290 which also out runs it pretty much everywhere.
Now down come's the 780TI pooping all over early adopters of the 780 and more so the titan buyers who thought they were getting a flagship card and foolishly paid $1000+ for them.
But its not all bad because heck man performance is performance and the 780ti is obviously needed to keep Nvidia in this race so we all look past its release but can't look past its premium pricing which is just another rip off of the customers @ 150$ over the competitor's pricing which closely competes at lower resolutions and fails to out perform @ 4k and in SLI/crossfire configurations.
Now all that would be just business as usual if Reviewer's were Educating about AMD's crossfire and high resolution performance wins over even the new and improved 780TI.
Instead they are quiet as a mouse to All AMD's Wins aside from pricing because well that's obvious and hard to ignore right. and rip AMD a new one over the downsides aka heat and noise which is totally justified and expected.
While for the nvidia side of things its all Christmas and Win's on the review reading in such a way that the 780ti wins in every category. failing to mention the Wattage use is getting up there as well as heat and fan noise, perhaps not up to 290x height's but much further than the GTX780.
All of these things have been pointed out on other review sites the good and the bad.

lol, at the end of the day its all about target marketing.... excluding the fanboys of course. Fanboys = omg its better, faster, cooler oh oh i gotta have it. where as most normal people will analyse the cost of the GPU in relation to its performance to which if applicable to them would do other little upgrades to it/their case if need be, if it all still fits into the equation of how much to spend. etc etcdo your research, read lots of reviews, ask questions(if any) then purchase and don't look back. pretty simple.....
most of you all come here to rage and fire shots to either side (great entertainment btw) reminds me of that Halo Red Vs Blue. more like "fanboys - Red Vs Green" oh hey hey - why Red first eh eh!?

Why exactly would I buy a GTX 780 Ti, when for a $100 more I can get TWO Radeon R9 290s in SLI and get twice the performance? The heat issue is there, but it ain't nothing an aftermarket cooler can't handle like the Accelero Xtreme 3.AMD wouldn't have flinched from the GTX 780 Ti's launch had it not been for their utterly terrible reference coolers.
SymphonyX7 - Saturday, November 9, 2013 - link
I meant Crossfire, not SLI. But you get the point. Have you seen those CF 290x vs SLI 780 Ti numbers? That's a ridiculous beatdown.TheinsanegamerN - Saturday, November 9, 2013 - link
you know, what i see from this, is that the 290x in uber mode is just as fast as the 780ti in most senarios, and is often a little faster. which should mean that the third party coolers that get slapped on these things should allow the 290x to soundly beat the 780ti. lets get the windforce 3x version of both these cards when they come out, and bench those for a more equal review.
