Compare any two graphics cards:
GeForce GTX 460 vs GeForce GTX 560 Ti
IntroThe GeForce GTX 460 has a GPU core clock speed of 675 MHz, and the 768 MB of GDDR5 RAM runs at 900 MHz through a 192-bit bus. It also features 336 Stream Processors, 56 Texture Address Units, and 24 Raster Operation Units.
Compare those specifications to the GeForce GTX 560 Ti, which features a clock frequency 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 features 384 SPUs, 64 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 560 Ti should be quite a bit faster than the GeForce GTX 460 overall. (explain)
Texel RateThe GeForce GTX 560 Ti should be much (more or less 39%) more effective at texture filtering than the GeForce GTX 460. (explain)
Pixel RateThe GeForce GTX 560 Ti should be quite a bit (approximately 62%) faster with regards to full screen anti-aliasing than the GeForce GTX 460, and 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.
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 largest amount of information (measured in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units 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 per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs 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 fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
