Compare any two graphics cards:
GeForce 8800 GTX vs Radeon HD 3870 1GB
IntroThe GeForce 8800 GTX makes use of a 90 nm design. nVidia has set the core speed at 575 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this card. It features 128 SPUs along with 64 TAUs and 24 ROPs.Compare those specs to the Radeon HD 3870 1GB, which comes with a GPU core clock speed of 775 MHz, and 1024 MB of GDDR4 RAM running at 1125 MHz through a 256-bit bus. It also is made up of 320(64x5) Stream Processors, 16 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce 8800 GTX should theoretically be just a bit superior to the Radeon HD 3870 1GB in general. (explain)
Texel RateThe GeForce 8800 GTX will be quite a bit (approximately 197%) better at anisotropic filtering than the Radeon HD 3870 1GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce 8800 GTX is the winner, but only just. (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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number 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 output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
