Introducing The GeForce GTX 770
In March 2012 the GeForce GTX 680 introducing countless new software, hardware, and architectural innovations that drew universal praise. Enabling this revolution was Kepler, our new GPU architecture that reduced power usage by 49 Watts when compared to the previous-generation GeForce GTX 580. This unprecedented improvement in efficiency had a second, significant benefit, in that it dramatically reduced heat output. Combined with a new and improved heatsink and fan, temperatures were reduced so considerably that performance could be ramped up by a massive 35%.
Today, we'?re unveiling the GeForce GTX 770, a new high-end gaming graphics card faster and more efficient than both the GeForce GTX 670, and the aforementioned GeForce GTX 680.
Introducing the new GeForce GTX 770.
Available now from all e-tailers and retailers at a recommended retail price of $399, the GeForce GTX 770 features the same desirable styling as the recently-released GeForce GTX 780, and compared to its predecessor is 15% faster thanks to higher clock speeds, 192 more CUDA Cores, and faster 7Gbps memory. The GTX 770 also supports our latest hardware-software enhancements, like GPU Boost 2.0, Overvolting, Display Overclocking, and ShadowPlay.

GeForce GTX 770 Performance
Leveraging its higher clock speeds, faster memory, and extra CUDA Cores, the GeForce GTX 770 is on average 15% faster than its predecessor, the GeForce GTX 670.
At 1920x1080, the GTX 770 handled the newly-released, performance-intensive Metro: Last Light with ease, hitting a speedy 61 frames per second with Very High Quality, 16x AF, and Very High Tessellation enabled. Compared to the GTX 670, the GTX 770 was 13% faster, and in the equally-demanding Crysis 3 it was 14% faster.
At 2650x1600, the GTX 770'?s enhancements gave it a big boost, enabling the GTX 770 to run 26% faster in Shogun 2: Total War, 24% faster in Sleeping Dogs, 20% faster in Battlefield 3, and 18% faster in Crysis 3.
GeForce GTX 770 SLI Performance
In SLI multi-GPU configurations, the GTX 770 is equally strong, improving frame rates by up to 98% when compared to single-GPU performance.
Further enhancing the SLI experience is our latest multi-GPU frame metering technology, which minimizes stuttering and other multi-GPU issues that have discussed at length on hardware sites in recent weeks. With our SLI evaluation tool, called FCAT, we?'ve been able to fine-tune SLI, ensuring that our Kepler GPUs offer the best multi-GPU experience to date.
Reference-design GeForce GTX 770s feature an all-new look, and a number of other refinements and enhancements, too. This isn?'t just for show; our new-generation design allows the GTX 770 to run cooler and quieter than its predecessor, even at higher speeds, whilst introducing extra CUDA Cores and faster memory.
On the Printed Circuit Board (PCB), on which all components are placed, we introduced an aluminum baseplate to help transfer heat away from the GPU and other board components, and on GPU itself we?'ve applied a new thermal interface material from renowned Japanese firm Shin-Etsu. Twice as effective as the thermal grease applied to GTX 680 GPUs, this seemingly small change allows us to push the GTX 770 harder and faster, and to reduce fan speeds when idle.
To collect the heat emitted by the GPU and VRAM, a high-performance copper vapor chamber has been placed in contact with the GPU. Like the GTX TITAN?s vapor chamber, its process of controlled evaporation cools the card faster and to a better degree than any conventional heatsink and heatpipe combo. This vapor-chambered heat is then dissipated by a large, dual-slot aluminum heatsink that?'s equipped with an extended fin stack that covers the entire area occupied by the GPU and VRAM; not just the area above the vapor chamber as on previous GeForce GTX graphics cards. This increases the cooling area and overall performance of the cooling system by a significant degree.
Finally, to remove the collected and dissipated heat, a rear-mounted fan constructed from an acoustic-dampening material blows it out through the exhaust at the rear of the computer?s chassis, and away from the card?s components.
The GTX 770?'s stunning exterior is comprised of cast aluminum, which dissipates heat more effectively than plastic. The fan, meanwhile, is surrounded by an injection-molded material that dissipates heat and reduces fan noise, and a clear polycarbonate window allows owners to monitor dust buildup in the nickel-plated heatsink fins.
On the exterior edge, the GeForce GTX logo is illuminated by LEDs. Using third-party tools, their intensity can be manually adjusted, or be set to brighten and dim automatically with the level of GPU utilization, adding a neat effect to windowed cases.
Together, these features and changes make the GeForce GTX 770 considerably quieter, and cooler than previous-generation GPUs, like the GeForce GTX 670.
On the software side, the GTX 770 packs-in a new adaptive temperature controller, reducing noise by keeping the GPU's fan speed at a more consistent level. Previously, GPU fans would reduce to a minimum speed when GPU usage and temperatures were sufficiently low. As temperatures raised once more, fans would noisily kick into high gear to bring temperatures back down. In contrast, the GTX 770's fan software minimizes the number of noticeable fan speed changes, making the user experience far more pleasant.
Our new adaptive temperature controls minimize fan speed fluctuations, making for a quieter, more pleasant user-experience.
GPU Boost 2.0: Temperature?s The Limit
In the days of the GeForce GTX 580, GPU speed was held back by synthetic benchmarks that pushed power usage to the limit, far beyond the levels typically seen when playing games. This ?worst case scenario? forced us to throttle speeds, leaving spare performance on the table. With the introduction of Kepler in 2012, a new hardware-software feature called GPU Boost solved the problem by continuously monitoring power usage, enabling GPUs to use every last ounce of performance without exceeding safety or comfort limits.
With GPU Boost, every application and game runs at a guaranteed, minimum Base Clock speed. If there?'s extra power available a Boost Clock is enabled, increasing clock speeds until the graphics card hits its predetermined Power Target (170 Watts on the GTX 680, for example). This dynamic clock speed adjustment is controlled by GPU Boost 1.0, which monitors a whole slew of data and makes real-time changes to speeds and voltages several times per second, maximizing performance in each and every application.
GPU Boost 1.0 enabled GPU owners to direct all available power to game performance for the very first time.
Having acquired data from hundreds of thousands of end-users in the year following the GTX 680?'s release, NVIDIA? engineers determined that GPU temperature was in fact a more common inhibitor to performance than power consumption. Subsequently, they developed GPU Boost 2.0 for the latest Kepler GPUs, which increases the Boost Clock until the GPU hits a predetermined 80C Temperature Target.
GPU Boost 2.0 increases performance to an even greater extent, compared to GPU Boost 1.0.
GPU Boost 2.0?'s other major advancement is the introduction of full user-control. Now, GTX 700 Series owners can tweak the Boost behavior by increasing or decreasing the Temperature Target via third-party software like EVGA Precision X. This enables users to manually change the Temperature Target, limiting or maximizing performance.
Combined with a watercooling setup that keeps temperatures low at all times, this feature is particularly powerful, allowing GPU Boost 2.0 to wring every last drop of performance out of the GPU.
Temperature Target places performance controls back in the hands of users.
Overvolting: Extra Overclocking For The Brave
GeForce GTX 770 owners who wish to push their cards to the limit will enjoy the new GPU Boost 2.0 controls discussed above, but for the most enthusiastic end-user we have one final addition of note: overvolting controls. Accessible through aforementioned third-party applications, overvolting allows users to push GPU usage beyond safe limits, increasing performance yet further.
Overvolting can increase performance by a substantial degree, if you're willing to use it.
Please be aware that overvolting may void the graphics card?s warranty, and that continued overvolting may cause the GPU?'s silicon to degrade at an advanced rate, ultimately causing it to die a premature death through electromigration. As such, we don'?t recommend the use of overvolting, but at the same time we don'?t wish to put artificial limitations on products you pay for.
Display Overclocking: Unleashing Your Monitor?s Potential
Many PC gamers play with VSync enabled to avoid unsightly image tearing that occurs when the frame rate is higher than the monitor?'s refresh rate. Most monitors are locked to 60Hz, limiting the max VSync frame rate to 60 frames per second. Thing is, 60Hz is a hang-up from the olden days of cathode ray tube technology, but we stick with it, simply because.
Unhappy with this stall in technological advancement, our engineers looked inside today?'s LCD and LED-backlit screens and discovered that many support higher refresh rates. For that reason we?'ve developed Display Overclocking, which allows GeForce GTX 770 owners to quickly and easily overclock their refresh rates via the same third-party tools that control GPU Boost 2.0. And of course, Display Overclocking works with Adaptive VSync too, allowing games to be played at 80Hz or more on a ?60Hz? screen, without tearing, and without the stuttering associated with normal VSync.
Display Overclocking works on faster 120Hz and 144Hz displays, too.
GeForce Experience: The Easiest Way To Optimize Your Games
GeForce Experience is NVIDIA's new application that can automatically keep GPU drivers up to date, and can optimize game settings with a single click, simplifying the process of getting the most from your PC, and your games. Great for those who want to spend time gaming, not tweaking, GeForce Experience recommends the best possible settings for your specific system configuration, allowing you to jump straight into a game without having to change options, drag sliders, or pick between one of eight similarly-named settings in an acronym-laced dropdown.
The latest version, 1.5, supports over 80 of the most popular English and Chinese titles, improves support for multiple system configurations and resolutions, and can tell you whether your system supports NVIDIA Shield PC game streaming.
GeForce Experience can simplify your life, too, notifying you of new driver releases and downloading them automatically should you so desire. This feature can also automatically download GeForce Experience support for entirely new titles, as well as new SLI and 3D Vision profiles, ensuring you receive the optimum experience whenever you load up a game.
