Compare any two graphics cards:
GeForce GTX 460 vs GeForce GTX 560 Ti
IntroThe GeForce GTX 460 features a core clock frequency of 675 MHz and a GDDR5 memory speed of 900 MHz. It also uses a 192-bit bus, and uses a 40 nm design. It features 336 SPUs, 56 Texture Address Units, and 24 Raster Operation Units.
Compare that to the GeForce GTX 560 Ti, which has a core clock speed of 822 MHz and a GDDR5 memory frequency of 1002 MHz. It also uses a 256-bit memory bus, and uses a 40 nm design. It is comprised of 384 SPUs, 64 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 560 Ti should perform quite a bit faster than the GeForce GTX 460 overall. (explain)
Texel RateThe GeForce GTX 560 Ti is a lot (more or less 39%) more effective at anisotropic filtering than the GeForce GTX 460. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 560 Ti is a better choice, by far. (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: Bandwidth is the max amount of data (measured in MB per second) that can be transported past 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 memory, 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 AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
