The only card we've seen with a better score in this test was the dual-GPU GeForce GTX 590, which is significantly more expensive. This is far faster than the Radeon HD 7970, which only managed 88fps. We are now seeing the first custom GTX 680 board designs pop up. It also introduces an automatic dynamic overclocking method which gives the card the leading edge, making it the fastest single GPU graphics card in the world. The card comes with massively improved performance per Watt. NVIDIA's dynamic overclocking algorithm works well and provides a nice speed boost for the card. With the card being part of the Lightning series, though, were more interested in the overclocking side of things and looking above you can see we pushed the core to 1200MHz or 1265MHz via Boost. Today NVIDIA released their new GeForce GTX 680 which is based on the companys brand-new Kepler architecture. It offers great performance at significantly reduced power consumption. Dirt 3, running at 1,920 x 1,080 with 4x anti-aliasing and Ultra detail, ran at an amazing 114fps. NVIDIA's GeForce GTX 680 was introduced just weeks ago and has taken the enthusiast market by storm. The card was extremely fast in our benchmarks. #NVIDIA GEFORCE GTX 680 2GB REVIEW FULL#This helps to overcome bottlenecks when not all of the card's cores are being used to their full capacity, in a similar way to how Turbo Boost works on Intel processors when they're running lightly-threaded applications. This dynamically increases the GPU's clock speed in 13MHz increments from its stock 1.01GHz up to a maximum of 1.058MHz where there is sufficient power and thermal headroom. Its performance is helped by what Nvidia calls GPU Boost. #NVIDIA GEFORCE GTX 680 2GB REVIEW WINDOWS#The card needs two six-pin PCI Express power connectors, and Nvidia recommends a 550-Watt power supply - this is no power-hungry monster like the dual-GPU GTX 590.ĭespite its relatively modest size and power requirements, this is an extremely powerful graphics card. NVidia GeForce GTX 680 Windows Vista, Windows 7, Windows 8, Windows XP, Windows Server 2003. This compares well to the AMD Radeon HD 7970 and its 277mm length, and you should have no problem fitting it in a medium-sized case. It's a fairly compact card, too, at just 252mm long. There are 1,536 CUDA cores, a 1.01GHz core clock speed and the card's 2GB of GDDR5 memory runs at a huge 1.5GHz. NVIDIAs dynamic overclocking algorithm works well and provides a nice speed boost for the card. Nvidia claims the GTX 680 is the "Fastest, most efficient GPU ever built", and it certainly has some impressive specifications. NVIDIAs GeForce GTX 680 was introduced just weeks ago and has taken the enthusiast market by storm.
