Compare any two graphics cards:
GeForce GTX 560 Ti vs Radeon R7 240
IntroThe GeForce GTX 560 Ti 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 is comprised of 384 SPUs, 64 TAUs, and 32 Raster Operation Units.
Compare all that to the Radeon R7 240, which uses a 28 nm design. AMD has clocked the core speed at 730 MHz. The DDR3 memory works at a speed of 900 MHz on this particular card. It features 320 SPUs as well as 20 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 560 Ti should in theory be a lot better than the Radeon R7 240 in general. (explain)
Texel RateThe GeForce GTX 560 Ti should be much (approximately 260%) faster with regards to AF than the Radeon R7 240. (explain)
Pixel RateThe GeForce GTX 560 Ti should be much (approximately 350%) faster with regards to AA than the Radeon R7 240, and will be capable of handling higher screen resolutions better. (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 largest amount of information (in units of MB per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units by the core 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 in a second.
Pixel Rate: Pixel rate is the maximum amount 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 number of colour 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
