Nvidia Corp. on Thursday introduced its third consumer graphics adapter based on the code-named Kepler architecture. At $399, the GeForce GTX 670 not only offers enthusiast-class performance in demanding video games, but is also quiet, energy efficient and can fit into many computer cases.
Nvidia GeForce GTX 680 is powered by a cut-down version of GK104 graphics processing unit - the same chip that is used for the GTX 680 and GTX 690 graphics boards - and features 1344 stream processors, 112 texture units, 32 raster operating units as well as 256-bit memory bus. The chip is clocked at 915MHz, whereas 2GB of GDDR5 memory operate at 6GHz. The new graphics card fully supports modern high-end features like DirectX 11.1, OpenGL 4.2, OpenCL 1.2, stereoscopic-3D, 4 multi-monitor capability, PhysX, 3-way multi-GPU, PCI Express 3.0 and so on.
The graphics board consumes up to 170W, which is not a lot for today's high-end graphics cards, and is 9.5" long, which is also considered normal for today's performance-mainstream solutions. The model GTX 670 requires two 6-pin PCI Express connectors. Reference design of the graphics card has one dual-link DVI-I, one dual-link DVI-D, one HDMI and one DisplayPort outputs.
Nvidia claims that the GeForce GTX 670 is considerably faster than the GeForce GTX 570 and in some games in 1920*1080 resolution it can be over 40% faster than AMD Radeon HD 7950.
By releasing GeForce GTX 670, Nvidia considerably widens addressable market for its GeForce Kepler family thanks to $399 price-point. Still, the GeForce GTX 670 is not a mainstream solution, but clearly a high-end one, based on its positioning. What should be kept in mind is that since the GK104 graphics processing unit made using 28nm process technology is not large (294mm2) and in the past Nvidia could sell various products based on chips with similar die size (and comparable cost) in $200 - $300 range without problems, the company has a lot of opportunities to further reduce pricing of the GTX 670.
The GeForce GTX 670-based graphics cards are available now from various add-in card suppliers, including ASL, Asustek Compter, Colorful, ECS, EVGA, Gainward, Galaxy, Gigabyte, Innovision 3D, Jetway, Leadtek, MSI, Palit, Point of View, PNY, Sparkle and Zotac.
