Compare any two graphics cards:
GeForce 9800 GTX vs Radeon HD 5750 512MB
IntroThe GeForce 9800 GTX has a GPU clock speed of 675 MHz, and the 512 MB of GDDR3 memory is set to run at 1100 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.Compare those specs to the Radeon HD 5750 512MB, which comes with core speeds of 700 MHz on the GPU, and 1150 MHz on the 512 MB of GDDR5 memory. It features 720(144x5) SPUs along with 36 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 5750 512MB should theoretically be a little bit better than the GeForce 9800 GTX overall. (explain)
Texel RateThe GeForce 9800 GTX is much (more or less 71%) better at AF than the Radeon HD 5750 512MB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 5750 512MB is a better choice, not by a very large margin though. (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 data (counted in megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
