Compare any two graphics cards:
GeForce GTX 580 3GB vs Radeon HD 6750 1GB
IntroThe GeForce GTX 580 3GB makes use of a 40 nm design. nVidia has clocked the core frequency at 772 MHz. The GDDR5 RAM is set to run at a speed of 1002 MHz on this particular card. It features 512 SPUs along with 64 Texture Address Units and 48 ROPs.Compare all of that to the Radeon HD 6750 1GB, which features clock speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 720 SPUs along with 36 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 580 3GB should be 201% faster than the Radeon HD 6750 1GB overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 580 3GB is quite a bit (approximately 89%) better at texture filtering than the Radeon HD 6750 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 580 3GB is the winner, and very much so. (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 (in units of MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at 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 video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
