GeForce GTX 660 Ti vs Geforce GTX 670
Intro
The GeForce GTX 660 Ti comes with a GPU core speed of 915 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1500 MHz through a 192-bit bus. It also is comprised of 1344 Stream Processors, 112 Texture Address Units, and 24 Raster Operation Units.Compare those specs to the Geforce GTX 670, which uses a 28 nm design. nVidia has clocked the core frequency at 915 MHz. The GDDR5 RAM runs at a frequency of 1500 MHz on this specific model. It features 1344 SPUs as well as 112 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
