Compare any two graphics cards:
GeForce 8800 GTS (G80) 320MB vs Radeon HD 5750 1GB
IntroThe GeForce 8800 GTS (G80) 320MB uses a 90 nm design. nVidia has set the core speed at 513 MHz. The GDDR3 RAM works at a frequency of 792 MHz on this specific card. It features 96 SPUs as well as 48 Texture Address Units and 20 Rasterization Operator Units.Compare those specifications to the Radeon HD 5750 1GB, which comes with a core clock speed of 700 MHz and a GDDR5 memory frequency of 1150 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 720(144x5) SPUs, 36 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 5750 1GB should be a small bit faster than the GeForce 8800 GTS (G80) 320MB overall. (explain)
Texel RateThe Radeon HD 5750 1GB will be a little bit (about 2%) more effective at AF than the GeForce 8800 GTS (G80) 320MB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 5750 1GB is a better choice, but only just. (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 data (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better 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 number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core 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 rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
