Compare any two graphics cards:
GeForce GTX 560 Ti vs Radeon HD 7870
IntroThe GeForce GTX 560 Ti features a core clock speed of 822 MHz and a GDDR5 memory frequency of 1002 MHz. It also features a 256-bit bus, and makes use of a 40 nm design. It is made up of 384 SPUs, 64 TAUs, and 32 ROPs.
Compare all that to the Radeon HD 7870, which comes with a clock frequency of 1000 MHz and a GDDR5 memory speed of 1200 MHz. It also features a 256-bit bus, and uses a 28 nm design. It is comprised of 1280 SPUs, 80 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Radeon HD 7870 should theoretically be a small bit superior to the GeForce GTX 560 Ti in general. (explain)
Texel RateThe Radeon HD 7870 is quite a bit (about 52%) more effective at AF than the GeForce GTX 560 Ti. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 7870 is superior to the GeForce GTX 560 Ti, 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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number 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 amount of colour ROPs by the the core clock speed. 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 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.
