Compare any two graphics cards:
GeForce 8800 GTX vs Radeon HD 5750 512MB
IntroThe GeForce 8800 GTX features a GPU core clock speed of 575 MHz, and the 768 MB of GDDR3 memory is set to run at 900 MHz through a 384-bit bus. It also features 128 SPUs, 64 TAUs, and 24 Raster Operation Units.Compare that to the Radeon HD 5750 512MB, which comes with GPU clock speed of 700 MHz, and 512 MB of GDDR5 RAM set to run at 1150 MHz through a 128-bit bus. It also features 720(144x5) SPUs, 36 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce 8800 GTX should theoretically be a bit superior to the Radeon HD 5750 512MB overall. (explain)
Texel RateThe GeForce 8800 GTX will be much (approximately 46%) faster with regards to AF than the Radeon HD 5750 512MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce 8800 GTX is superior to the Radeon HD 5750 512MB, 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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
