Compare any two graphics cards:
GeForce GTX 560 Ti vs Radeon HD 3870 X2 512MB
IntroThe GeForce GTX 560 Ti has a core clock speed of 822 MHz and a GDDR5 memory speed of 1002 MHz. It also uses a 256-bit bus, and uses a 40 nm design. It is made up of 384 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.Compare those specifications to the Radeon HD 3870 X2 512MB, which makes use of a 55 nm design. AMD has set the core speed at 825 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this model. It features 320(64x5) SPUs along with 16 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the GeForce GTX 560 Ti should theoretically be a bit superior to the Radeon HD 3870 X2 512MB in general. (explain)
Texel RateThe GeForce GTX 560 Ti should be much (about 99%) better at texture filtering than the Radeon HD 3870 X2 512MB. (explain)
Pixel RateThe Radeon HD 3870 X2 512MB should be a little bit (approximately 0%) more effective at FSAA than the GeForce GTX 560 Ti, and will be able to handle higher resolutions better. (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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number 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 applied in one second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
