Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs Radeon HD 5750 512MB
IntroThe GeForce 8800 GTS (G80) 640MB comes with core clock speeds of 513 MHz on the GPU, and 792 MHz on the 640 MB of GDDR3 RAM. It features 96 SPUs as well as 48 TAUs and 20 ROPs.Compare those specifications to the Radeon HD 5750 512MB, which has GPU core speed of 700 MHz, and 512 MB of GDDR5 memory set to run at 1150 MHz through a 128-bit bus. It also is made up of 720(144x5) Stream Processors, 36 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 5750 512MB will be 16% quicker than the GeForce 8800 GTS (G80) 640MB overall, due to its higher bandwidth. (explain)
Texel RateThe Radeon HD 5750 512MB will be a bit (approximately 2%) better at texture filtering than the GeForce 8800 GTS (G80) 640MB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 5750 512MB is the winner, though not 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 are applied in one second. This is calculated 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount 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 number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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 - the lower the bandwidth is, the lower the potential to get to the max fill rate.
