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

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 570 should be 6% faster than the GeForce GTX 660 Ti overall, due to its higher data rate. (explain)
Texel RateThe GeForce GTX 660 Ti will be quite a bit (about 133%) better at anisotropic filtering than the GeForce GTX 570. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 570 is a better choice, and very much so. (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 information (counted in MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If 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 higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
