Compare any two graphics cards:
GeForce GTX 280 vs GeForce GTX 560 Ti
IntroThe GeForce GTX 280 features a clock frequency of 602 MHz and a GDDR3 memory frequency of 1107 MHz. It also makes use of a 512-bit memory bus, and uses a 65 nm design. It is comprised of 240 SPUs, 80 TAUs, and 32 Raster Operation Units.
Compare those specifications to the GeForce GTX 560 Ti, which makes use of a 40 nm design. nVidia has set the core frequency at 822 MHz. The GDDR5 RAM is set to run at a frequency of 1002 MHz on this particular model. It features 384 SPUs as well as 64 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 280 should perform a small bit faster than the GeForce GTX 560 Ti in general. (explain)
Texel RateThe GeForce GTX 560 Ti will be a little bit (approximately 9%) faster with regards to AF than the GeForce GTX 280. (explain)
Pixel RateThe GeForce GTX 560 Ti should be a lot (approximately 37%) more effective at FSAA than the GeForce GTX 280, and also should be capable of handling higher screen resolutions without losing too much performance. (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 (counted in MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If 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 high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
