Compare any two graphics cards:
GeForce GTX 295 vs Radeon HD 3870 X2 512MB
IntroThe GeForce GTX 295 makes use of a 55 nm design. nVidia has set the core speed at 576 MHz. The GDDR3 memory is set to run at a speed of 999 MHz on this specific card. It features 240 SPUs along with 80 TAUs and 28 Rasterization Operator 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 memory runs at a speed of 900 MHz on this specific card. It features 320(64x5) SPUs along with 16 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the GeForce GTX 295 should perform a lot faster than the Radeon HD 3870 X2 512MB overall. (explain)
Texel RateThe GeForce GTX 295 is quite a bit (more or less 249%) faster with regards to texture filtering than the Radeon HD 3870 X2 512MB. (explain)
Pixel RateThe GeForce GTX 295 should be quite a bit (more or less 22%) more effective at anti-aliasing than the Radeon HD 3870 X2 512MB, and also should be able to handle higher screen resolutions while still performing well. (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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 the video card can possibly record to the local memory in one 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 - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
