Compare any two graphics cards:
GeForce GTX 570 vs GeForce GTX 660 Ti
IntroThe GeForce GTX 570 features a core clock speed of 732 MHz and a GDDR5 memory frequency of 950 MHz. It also features a 320-bit bus, and uses a 40 nm design. It is made up of 480 SPUs, 60 Texture Address Units, and 40 ROPs.
Compare all of that to the GeForce GTX 660 Ti, which has a clock speed of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 192-bit bus, and uses a 28 nm design. It is made up of 1344 SPUs, 112 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 570 will be 6% faster than the GeForce GTX 660 Ti in general, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 660 Ti should be a lot (more or less 133%) more effective at AF than the GeForce GTX 570. (explain)
Pixel RateThe GeForce GTX 570 should be a lot (about 33%) more effective at full screen anti-aliasing than the GeForce GTX 660 Ti, and also should be capable of handling higher resolutions more effectively. (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 (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units of the card 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 per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip 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 Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
