One other notable improvement to the GTX 680 comes in the form of improved PhysX performance. Support for Cyberlink PowerDirector and Arcsoft MediaConverter is promised for a later date.

Unfortunately, software developers need to incorporate NVENC support in their software, so at launch you're limited to using Cyberlink's Media Expresso.

That means 1080p videos encode up to eight times faster than real time, depending on your chosen quality setting, so a 16-minute-long 1080p, 30fps video takes approximately 2 minutes to complete. 'If you're anything like us, then nothing gets you more excited than realistic cloth animations and individually animated strands of hair.' And so, in keeping with Nvidia's new power-saving attitude, the NVENC encoder consumes much less power, while also being four times as fast. While previous GTX cards sped up encoding using the GPU's CUDA cores, it resulted in increased power consumption. If you've ever tried to encode H.264 video, you'll know that it's a time-consuming process. Of course, this being a reference card, you can expect manufacturers to come up with their own crazy cooling solutions once they start shipping 680s.Īnother neat feature of the 680 is a new hardware-based H.264 video encoder called NVENC. It features special acoustic dampening material around the fan, a triple heat pipe design, and a redesigned fin stack that has been shaped for better airflow. The reference card has an all-new cooling setup that's much kinder on your ears a godsend for anyone that ever had to endure the jet engine sounds of the GTX 400 series. The reduced TDP also results in reduced heat, meaning it's easier to keep cool.

'Clearly, the 680 is a more powerful beast than its predecessor, but it's also more practical too.' Also notable is the reduced power consumption of the card, which has a TDP of 195 Watts, compared to 250 Watts in a GTX 580, meaning you only need two six-pin connectors, and you can run it from a much smaller power supply. That goes for 3D vision surround, meaning you don't have to splurge on an SLI setup if you're into giving yourself a headache.

The four display outputs mean you can drive four monitors (at up to 4K 3840x2160 resolution!) at once from a single card. Multiple acronyms aside, just what do you get if you plump down your hard-earned cash for a GTX 680? Quite a bit as it goes: 1536 CUDA Cores, 128 Texture Units, 32 ROP Units, 1Ghz Base Clock, 2GB GDDR5 RAM 6Ghz, 128.8 GigaTexels/sec Filtering Rate, 28nm Fabrication, 2x Dual Link DVI, 1x HDMI, 1x DisplayPort, 2x 6-pin Power Connectors, and a 195 Watt TDP.īased on specs alone, the 680 is a more powerful beast than its predecessor, but it's also more practical too. It features a new Streaming Multiprocessor (SMX) design, GPU Boost, new FX and TX Anti-aliasing (FXAA/TXAA) technology, Adaptive VSync, support for up to four monitors (including 3D Vision Surround), and-most interestingly of all-much reduced power consumption with an increased focus on performance per watt. Aside from a few optimisations from Epic, most of that comes down to the new 28nm Kepler architecture that the 680 is based on. The answer, it turns out, was also unveiled at this year's GDC in the form of Nvidia's brand-new GTX 680 GPU, a single one of which easily powers the Samaritan demo.

And this left us wondering: if it took so much power to run the demo, what chance would the next generation of console and PC gamers have to experience it? The problem was, Samaritan didn't exactly run on your average gaming PC, requiring three Nvidia GTX 580 GPUs at a cost of thousands of dollars, as well as a power supply that brought Greenpeace members out in a cold sweat. The demo was so impressive that Epic decided to show it again at this year's GDC, with vice president Mark Rein reiterating that Samaritan is its vision for the next generation-a 'screw you' to the naysayers predicting that graphical prowess will play second fiddle to features and functionality. It was-and still is-an impressive demo, showcasing smoothly tessellated facial features, point light reflections, and judicious use of movie-style bokeh. At GDC 2011, Epic Games (maker of Gears of War) unveiled Samaritan, an eye-popping technical demo that showed what was possible with Unreal Engine 3 and a seriously hardcore PC.
