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 clocked the core frequency at 576 MHz. The GDDR3 RAM runs at a frequency of 999 MHz on this particular model. It features 240 SPUs as well as 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 clocked the core speed at 825 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this card. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the GeForce GTX 295 should be 94% quicker than the Radeon HD 3870 X2 512MB in general, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 295 should be quite a bit (about 249%) better at anisotropic filtering than the Radeon HD 3870 X2 512MB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 295 is superior to the Radeon HD 3870 X2 512MB, 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. 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 transferred across the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, the result 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, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units of the card by the core 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 in one second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
