GeForce GTX 560 vs GeForce GTX 660 Ti

Intro

The GeForce GTX 560 has a GPU clock speed of 810 MHz, and the 1024 MB of GDDR5 RAM runs at 1001 MHz through a 256-bit bus. It also is comprised of 336 Stream Processors, 56 TAUs, and 32 ROPs.

Compare those specifications to the GeForce GTX 660 Ti, which makes use of a 28 nm design. nVidia has set the core frequency at 915 MHz. The GDDR5 memory works at a frequency of 1500 MHz on this specific card. It features 1344 SPUs as well as 112 Texture Address Units and 24 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock 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 output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
