Compare any two graphics cards:
GeForce GTX 560 Ti vs Radeon R7 240
IntroThe GeForce GTX 560 Ti features a GPU core speed of 822 MHz, and the 1024 MB of GDDR5 RAM runs at 1002 MHz through a 256-bit bus. It also is made up of 384 SPUs, 64 TAUs, and 32 Raster Operation Units.
Compare that to the Radeon R7 240, which features clock speeds of 730 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. 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 theoretically be quite a bit superior to the Radeon R7 240 overall. (explain)
Texel RateThe GeForce GTX 560 Ti will be a lot (approximately 260%) more effective at AF than the Radeon R7 240. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 560 Ti is superior to the Radeon R7 240, by a large margin. (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 data (measured in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
