Compare any two graphics cards:
GeForce GTX 560 Ti vs Radeon R7 240
IntroThe GeForce GTX 560 Ti has core speeds of 822 MHz on the GPU, and 1002 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs as well as 64 Texture Address Units and 32 ROPs.
Compare all of that to the Radeon R7 240, which comes with clock speeds of 730 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 320 SPUs along with 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 560 Ti should perform quite a bit faster than the Radeon R7 240 overall. (explain)
Texel RateThe GeForce GTX 560 Ti will be quite a bit (approximately 260%) faster with regards to texture filtering than the Radeon R7 240. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 560 Ti is a better choice, and very much so. (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 transported across the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
