![]() In all, it generates about 43 dBA, versus the 48 or so dBA that the GTX 680 produced. The GTX 780 includes the same heat sink that the Titan does: a copper vapor chamber and dual-slot aluminum heatsink along with a blower-style fan. Longtime Nvidia customers who purchased early GeForce cards will appreciate that Nvidia has made a concerted effort to reduce the GTX 780’s fan noise. Nvidia Realistic waves, realistic faces: Two technologies the GTX 780 is designed to accelerate. But using this feature does pose a risk of damaging the GPU, and users must acknowledge the risk before they can unlock the technology. Third-party cards may include this feature, however, enabling users to increase the chip’s operating voltage, and thus permitting increased clock multipliers. Nvidia said that it would not allow a second type of performance increase, known as overvoltaging, on its own cards. Users can increase the thermal temperature limit to increase performance further. If Nvidia’s on-chip logic thinks that the temperature will soon exceed that figure, the chip steps down its clock speed until it reaches a safe point.īoost 2.0 also includes new tools for tweaking the GTX 780’s performance. Boost 1.0 and Boost 2.0 are essentially the same, but Nvidia replaced the power target with a specific temperature target: 80 degrees C. With Boost 2.0, Nvidia now uses on-chip thermal sensors for more accurate measurement. Early versions of the Boost technology were essentially the same as Intel’s Turbo Boost and other overclocking techniques used across the industry: They ramped up clock speeds as fast as possible, within a given power envelope, which meant that exceeding that power threshold could raise chip temperatures to dangerous levels. Nvidia has improved the GPU Boost capabilities within the new card, so it can run as fast as possible without overheating. ![]() The board itself is 10.5 inches long, and includes two dual-link DVIs, a HDMI connector, and a DisplayPort connector, to boot. Peddie said that he was quite impressed with the card’s performance. That figure includes graphics cards that cost $250 and above, however, so it’s likely that $600 cards will slice off just a small fraction of that. “They’re going to be using us for gaming and it’s going to be an integral part of their gaming experience.”Īs to how many people are going to buy a $649 graphics card (as opposed to an entire new PC, say) analyst Jon Peddie of Jon Peddie Research says that the enthusiast graphics card market remains relatively healthy: about 3 million units were sold last year. “Someone is making an investment in their gaming experience over the next few days,” Walker said. Nvidia Nvidia’s GeForce Experience hardware optimization engine is now out of beta. In situations where performance demands it, however, Nvidia has added its Boost 2.0 technology, which runs the card as fast as possible within a specified temperature envelope. Buyers can expect the GTX 780 to be quieter than previous generations of Nvidia cards too, thanks to better fan management. To assist gamers who want to plug in a GTX 780 card, sit down, and begin playing, Nvidia has brought its GeForce Experience out of beta, providing an automated configurations experience and managing the downloads and updates of Nvidia’s driver software. The 780 supports both DirectX 11.0 tessellation, for improved rendering of 3D objects, and Nvidia’s PhysX physics enhancements. For gamers who really want to shell out, pairing two GTX 780 cards in SLI mode will improve performance by 75 percent over a single GTX 780 card, Nvidia said.īasically, Nvidia is positioning the GTX 780 for enthusiast PC gamers who are willing to pony up for a superior rig, running at the maximum graphics settings and screen resolutions, with high levels of antialiasing. You’ll have to move fast, though: The GTX 780 will officially replace the GTX 680.) Nvidia also claims that the GTX 780 outperforms the $400 AMD HD7970 graphics card by an average of about 30 to 35 percent however, that AMD card debuted at the end of 2011. (That card’s price now hovers at about $470, temporarily providing a lower-cost alternative if the GTX 780 is still too rich for your blood. Nvidia claims that the GTX 780 will offer, on average, about 35 percent better graphics performance than the GeForce GTX 680, which Nvidia launched a year ago.
