The GTX 770’s stunning exterior is comprised of cast aluminum, which dissipates heat more effectively than plastic. This increases the cooling area and overall performance of the cooling system by a significant degree.įinally, 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 computers chassis, and away from the cards components. This vapour-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 vapour chamber as on previous GeForce GTX graphics cards. Like the GTX TITANs vapour chamber, its process of controlled evaporation cools the card faster and to a better degree than any conventional heatsink and heatpipe combo. To collect the heat emitted by the GPU and VRAM, a high-performance copper vapour chamber has been placed in contact with the GPU. 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.
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. 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. Reference-design GeForce GTX 770s feature an all-new look, and a number of other refinements and enhancements, too. 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. In SLI multi-GPU configurations, the GTX 770 is equally strong, improving frame rates by up to 98% when compared to single-GPU performance.įurther enhancing the SLI experience is our latest multi-GPU frame metering technology, which minimises stuttering and other multi-GPU issues that have discussed at length on hardware sites in recent weeks. Compared to the GTX 670, the GTX 770 was 13% faster, and in the equally-demanding Crysis 3 it was 14% faster.Īt 2650×1600, 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 and 18% faster in Crysis 3. 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.Īt 1920×1080, 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.
The GTX 770 also supports our latest hardware-software enhancements, like GPU Boost 2.0, Overvolting, Display Overclocking, and ShadowPlay. 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.Īvailable now from all e-tailers and retailers at a recommended retail price of £329, 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. Combined with a new and improved heatsink and fan, temperatures were reduced so considerably that performance could be ramped up by a massive 35%. This unprecedented improvement in efficiency had a second, significant benefit, in that it dramatically reduced heat output. 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. In March 2012 the GeForce GTX 680 introducing countless new software, hardware, and architectural innovations that drew universal praise.
