From X-bit Labs: Nvidia Corp. on Thursday unleashed its new graphics card based on Kepler architecture that the company positions as an ultimate solution for gamers. The novelty is based on the well-known GK104 chip with 1344 stream processors and thus provides excellent performance for modern video games. However, given positioning of the GeForce GTX 660 Ti product, the price tag of $299 seems to be too high.
Nvidia GeForce GTX 660 Ti graphics card is based on a cut-down version of the GK104 graphics processing unit (GPU) made using 28nm fabrication process, the same chip that is used on high-end models GTX 670 and 680. The model GTX 660 Ti has 1344 stream processing units, 112 texture units, 24 render back ends, 7 tessellation engines and 192-bit memory controller. Nvidia clocks the GK104 chip of GTX 660 Ti at 915MHz and recommends partners to install 2GB of GDDR5 memory clocked at 6008MHz onto the GeForce GTX 660 Ti graphics cards.
Given its Kepler origins, the GeForce GTX 660 Ti supports contemporary capabilities like DirectX 11.1, OpenGL 4.2, OpenCL 1.2, stereoscopic-3D, 4 multi-monitor output, PhysX, 4-way multi-GPU, PCI Express 3.0 and so on.
According to Nvidia itself, the GTX 660 Ti is 41% faster on average than the GeForce GTX 560 Ti from 2011 and can successfully compete against AMD Radeon HD 7950 that has recommended price-tag of $349. According to performance tests conducted by X-bit labs, in some cases the GeForce GTX 660 Ti is faster than the Radeon HD 7950, but in some cases the GTX 660 Ti fails to beat even its direct rival, the Radeon HD 7870 1GHz Edition. One advantage that the GeForce GTX 660 Ti clearly has over competing solutions from AMD is relatively low power consumption (no more than 150W in peak case scenario) and resulting short design of printed-circuit board, which means that the GTX 660 Ti can be installed into almost any computer case.
