Nvidia Unleashes GeForce GTX 670: Hardcore Gaming Becomes More Affordable.

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.
