Compare any two graphics cards:
GeForce GTX 460 vs GeForce GTX 560 Ti
IntroThe GeForce GTX 460 has a GPU clock speed of 675 MHz, and the 768 MB of GDDR5 memory is set to run at 900 MHz through a 192-bit bus. It also features 336 Stream Processors, 56 TAUs, and 24 ROPs.
Compare those specs to the GeForce GTX 560 Ti, which uses a 40 nm design. nVidia has clocked the core speed at 822 MHz. The GDDR5 memory is set to run at a frequency of 1002 MHz on this specific card. It features 384 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 560 Ti should in theory perform quite a bit faster than the GeForce GTX 460 in general. (explain)
Texel RateThe GeForce GTX 560 Ti should be quite a bit (approximately 39%) more effective at AF than the GeForce GTX 460. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 560 Ti is the winner, by a large margin. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video 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 most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
