Compare any two graphics cards:
GeForce GTX 275 vs GeForce GTX 580 3GB
IntroThe GeForce GTX 275 has a GPU clock speed of 633 MHz, and the 896 MB of GDDR3 memory runs at 1134 MHz through a 448-bit bus. It also is made up of 240 Stream Processors, 80 Texture Address Units, and 28 ROPs.Compare those specifications to the GeForce GTX 580 3GB, which makes use of a 40 nm design. nVidia has set the core frequency at 772 MHz. The GDDR5 memory works at a speed of 1002 MHz on this card. It features 512 SPUs along with 64 Texture Address Units and 48 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 580 3GB should be quite a bit faster than the GeForce GTX 275 in general. (explain)
Texel RateThe GeForce GTX 275 will be just a bit (about 2%) more effective at AF than the GeForce GTX 580 3GB. (explain)
Pixel RateThe GeForce GTX 580 3GB should be quite a bit (approximately 109%) faster with regards to AA than the GeForce GTX 275, and also capable of handling higher resolutions without losing too much performance. (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 megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core 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 processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
