Compare any two graphics cards:
GeForce GTX 580 3GB vs Radeon HD 5750 1GB
IntroThe GeForce GTX 580 3GB features a core clock frequency of 772 MHz and a GDDR5 memory frequency of 1002 MHz. It also uses a 384-bit bus, and makes use of a 40 nm design. It features 512 SPUs, 64 Texture Address Units, and 48 Raster Operation Units.Compare all of that to the Radeon HD 5750 1GB, which comes with GPU clock speed of 700 MHz, and 1024 MB of GDDR5 RAM running at 1150 MHz through a 128-bit bus. It also features 720(144x5) Stream Processors, 36 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 580 3GB should be 161% quicker than the Radeon HD 5750 1GB overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTX 580 3GB will be quite a bit (more or less 96%) faster with regards to anisotropic filtering than the Radeon HD 5750 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 580 3GB is the winner, by a large margin. (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 maximum amount of information (measured in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card 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 processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
