Compare any two graphics cards:
GeForce GTX 480 vs GeForce GTX 560
IntroThe GeForce GTX 480 features a core clock frequency of 700 MHz and a GDDR5 memory speed of 924 MHz. It also uses a 384-bit memory bus, and uses a 40 nm design. It is comprised of 480 SPUs, 60 Texture Address Units, and 48 ROPs.
Compare those specifications to the GeForce GTX 560, which comes with a clock speed of 810 MHz and a GDDR5 memory speed of 1001 MHz. It also features a 256-bit memory bus, and uses a 40 nm design. It features 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 480 should in theory be quite a bit faster than the GeForce GTX 560 overall. (explain)
Texel RateThe GeForce GTX 560 is a little bit (approximately 8%) more effective at texture filtering than the GeForce GTX 480. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 480 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 maximum amount of information (in units of MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the bus 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 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs 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 many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
