Compare any two graphics cards:
GeForce GTX 560 Ti vs Radeon HD 7850
IntroThe GeForce GTX 560 Ti uses a 40 nm design. nVidia has set the core speed at 822 MHz. The GDDR5 memory works at a speed of 1002 MHz on this specific model. It features 384 SPUs along with 64 Texture Address Units and 32 ROPs.
Compare all of that to the Radeon HD 7850, which uses a 28 nm design. AMD has set the core speed at 860 MHz. The GDDR5 memory is set to run at a speed of 1200 MHz on this model. It features 1024 SPUs along with 64 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon HD 7850 should theoretically be a bit faster than the GeForce GTX 560 Ti overall. (explain)
Texel RateThe Radeon HD 7850 should be a bit (approximately 5%) more effective at texture filtering than the GeForce GTX 560 Ti. (explain)
Pixel RateThe Radeon HD 7850 is just a bit (about 5%) better at AA than the GeForce GTX 560 Ti, and also capable of handling higher screen resolutions without slowing down too much. (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 data (counted in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
