Compare any two graphics cards:
GeForce 8800 GTS (G92) vs Radeon HD 3870 512MB
IntroThe GeForce 8800 GTS (G92) comes with a core clock speed of 650 MHz and a GDDR3 memory frequency of 970 MHz. It also makes use of a 256-bit bus, and makes use of a 65 nm design. It is made up of 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.Compare all that to the Radeon HD 3870 512MB, which makes use of a 55 nm design. AMD has clocked the core speed at 775 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this specific card. It features 320(64x5) SPUs as well as 16 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce 8800 GTS (G92) should theoretically be a small bit superior to the Radeon HD 3870 512MB overall. (explain)
Texel RateThe GeForce 8800 GTS (G92) should be a lot (more or less 235%) faster with regards to anisotropic filtering than the Radeon HD 3870 512MB. (explain)
Pixel RateThe Radeon HD 3870 512MB will be a bit (approximately 19%) better at anti-aliasing than the GeForce 8800 GTS (G92), and able to handle higher screen resolutions more effectively. (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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
