Compare any two graphics cards:
GeForce 9800 GTX vs Radeon HD 6770
IntroThe GeForce 9800 GTX features a clock speed of 675 MHz and a GDDR3 memory frequency of 1100 MHz. It also makes use of a 256-bit memory bus, and uses a 65 nm design. It is made up of 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.Compare those specifications to the Radeon HD 6770, which has a GPU core clock speed of 900 MHz, and 512 MB of GDDR5 memory running at 1050 MHz through a 128-bit bus. It also features 800 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 9800 GTX should perform a small bit faster than the Radeon HD 6770 overall. (explain)
Texel RateThe GeForce 9800 GTX should be a small bit (about 20%) better at texture filtering than the Radeon HD 6770. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 6770 is superior to the GeForce 9800 GTX, by a large margin. (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 max amount of information (counted in megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the 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 amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out 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 rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
