Compare any two graphics cards:
GeForce GTX 560 Ti vs GeForce GTX 660 Ti
IntroThe GeForce GTX 560 Ti makes use of a 40 nm design. nVidia has clocked the core speed at 822 MHz. The GDDR5 RAM is set to run at a frequency of 1002 MHz on this specific card. It features 384 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.
Compare all that to the GeForce GTX 660 Ti, which has a GPU core clock speed of 915 MHz, and 2048 MB of GDDR5 memory running at 1500 MHz through a 192-bit bus. It also is made up of 1344 Stream Processors, 112 Texture Address Units, and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 660 Ti will be 12% faster than the GeForce GTX 560 Ti overall, due to its greater data rate. (explain)
Texel RateThe GeForce GTX 660 Ti is a lot (approximately 95%) better at anisotropic filtering than the GeForce GTX 560 Ti. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 560 Ti is superior to the GeForce GTX 660 Ti, though only just barely. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 applied per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher 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 one second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure 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 drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
