Compare any two graphics cards:
GeForce GTX 560 Ti vs Radeon HD 6850
IntroThe GeForce GTX 560 Ti features a core clock frequency of 822 MHz and a GDDR5 memory speed of 1002 MHz. It also uses a 256-bit memory bus, and makes use of a 40 nm design. It is comprised of 384 SPUs, 64 TAUs, and 32 Raster Operation Units.
Compare all of that to the Radeon HD 6850, which uses a 40 nm design. AMD has clocked the core frequency at 775 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this model. It features 960 SPUs as well as 48 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 560 Ti should be 0% faster than the Radeon HD 6850 in general, due to its greater data rate. (explain)
Texel RateThe GeForce GTX 560 Ti will be a lot (about 41%) more effective at anisotropic filtering than the Radeon HD 6850. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 560 Ti is superior to the Radeon HD 6850, but not 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: Bandwidth is the maximum amount of information (measured in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units of the card by the core clock 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 processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core 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 also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
