Meet 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.

    thats the wholesale price its not nvidia that charges so much is the resellers. the profit nvidia makes per gpu is very low but the reseller make alot of money, also the new amd r9 290 is going for $255 per unit at wholesale price and the r9 280x is going for $160 dollar per unit. you have to also remember thats the distributer price not the manufacturer price,witch should be alot lower. i know the gtx 780 at manufacturer price sells from $200 to $280 depending on brand.

    so remember this is america were they sell you something made in china for 1 dollar for 10 dollars

    While those numbers are interesting, your conclusion is wrong. The $700 are what NVidia wants the customer to pay for the card, not what the reseller wants:
    "Pricing is expected to start at $699"

    So it's not the seller who makes 100% profit, it's NVidia.

    remember that the reseller has to buy the card, pay import taxes, transportation and others, try to sell it and if the card goes unsold they have to sell it in a few month at discounts prices. Also in the case of psychical stores they have to keep building costs, employees, more taxes, etc. So what you are describing happens in every industry. Also and maybe in first place where are you getting those numbers from?

    OK, so either Brian has lost his Nexus 5 or its benchmark boosting, cause something has to be going on here.

    Wow oc results are impressive. Where are the Lightning and Windforce versions?

    la ventaja frente a una 290x es mínima pero la diferencias de precio no cuando se mejore la refrigeración de la 290x, al fin y al cabo la competencia nos beneficia a todos

    HD7990 can be gotten for as low as £400 in the UK at the moment (or £480 with a PSU or a M/B), so anyone wanting the ultimate in single CARD performance would bet better off buying that anyway.

    Obviously noise and heat will still be an issue, but if you're going to ignore the GTX 780 Ti's price, we can ignore those factors (thankfully microstuttering is mostly a non-issue these days since frame pacing has resolved that in everything except DX9 for now).

    If the price of the 780 Ti were to drop 10-20%, I'd consider buying one, but as it is I simply can't justify it, even if affording it isn't a problem.

    Anand / Ryan

    I would love to see a comparison of the 290 , 290x 780, 780 Ti with water coolers working efficiently. I believe that anyone spending $600 on a Gfx card would be able to spend an additional 100-200$ for a cool setup.

    Further i would love to see if there is any performance increase due to increased cooling( With respect to boost states both Nv and AMD.

    Any comments please let me know

  • GUNN3R - Friday, November 29, 2013 - link

    Is there an update in scores with latest drivers?

    I really wish you guys had included useful resolutions. You realize the VAST majority of people, even enthusiasts, have 1080p screens right?

    You can do ur uber testing for your own personal concerns but it should be standing policy to include 1080p testing for everything. That's the resolution of screen that people have.
