Meet The GeForce GTX 780

As we previously mentioned, the GTX 780 is very much a Titan Mini in a number of ways. This goes for not only the architecture, features, and performance, but as it turns out it will be the case for the design too. For the reference GTX 780 NVIDIA will be straight-up reusing the GTX Titan’s board design, from the PCB to the cooler, and everything in between.

As a result the reference GTX 780 inherits all of the great things about the GTX Titan’s design. We won’t go into significant detail here – please read our GTX Titan review for a full breakdown and analysis of Titan’s design – but in summary this means we’re looking at a very well built blower design almost entirely constructed out of metal. GTX 780 is 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 that the reference GTX 780 like Titan before it is an extremely quiet card despite the fact that it’s a 250W blower design, while it also maintains the solid feel and eye-catching design of GTX Titan.

Drilling down, the PCB is also a re-use from Titan. It’s the same GK110 GPU mounted on the same PCB with the same 6+2 phase power design. This is part of the reason that GTX 780 has the same TDP as GTX Titan, while at the same time giving GTX 780 as much or more TDP headroom than Titan itself. 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.

Also being carried over from Titan is GPU Boost 2.0, which was first introduced there and has since been added to additional products (many GeForce 700M products already have it). GPU Boost is essentially a further min-maxed turbo scheme that more closely takes into account temperatures and GPU leakage characteristics to determine what boost bins can be used while staying below TDP. It’s more temperature dependent than the original GPU Boost and as a result more variable, but in cooler situations it allows tapping into that thermal headroom to hit higher clockspeeds and greater performance, TDP allowing. At the same time this means GTX 780 also gains GPU Boost 2.0’s temperature target functionality, which allows users to cap boost by temperature as well as TDP. As with Titan this limit is 80C by default, with the idea being that adjusting the limit is a proxy for adjusting the performance of the card and the amount of noise it generates.

    Excellent choice for less money than Titan! :-)

    "NVIDIA will be pricing the GTX 680 at $650, $350 below the GTX Titan and GTX 690, and around $200-$250 more than the GTX 680."

    I think you mean the 780?

    Thanks. Fixed.

    compared to titan it sure is a better value, but compared to the hight end 2 years ago its twice as much ( titan vs 580 ; 780 vs 570 ; 680 vs 560)
    NVIDIA is slowly geting people acoustmed to hight prices again,
    im gona wait for AMD to see what she can bring to the table
  • Hrel - Friday, May 24, 2013 - link

    She? AMD is a she now?
  • SevenWhite7 - Monday, July 8, 2013 - link

    Yeah, 'cause AMD's more bang-for-the-buck.
    Basically, NVidia's 'he' 'cause it's always the most powerful, but also costs the most.
    AMD's 'she' 'cause it's always more efficient and reasonable.
    I'm a guy, and guys are usually more about power and girls are more about the overall package.
    Just my experience, anyway, and this is just me being dumb trying to explain it with analogies =P

    bang for your buck has changed a bit just sold my 7950 added 80 bucks and bought a evga acx 780 b stock
  • cknobman - Thursday, May 23, 2013 - link

    At $650 I am just not seeing it. In fact I dont even see this card putting any pressure on AMD to do something.

    I'd rather save $200+ and get a 7970GE. If Nvidia really wants to be aggressive they need to sell this for ~$550.
  • chizow - Thursday, May 23, 2013 - link

    Nvidia has the GTX 770 next week to match up against the 7970GE in that price bracket, the 780 is clearly meant to continue on the massive premiums for GK110 flagship ASIC started by Titan. While it may not justify the difference in price relative to 7970GHz it's performance, like Titan, is clearly in a different class.
