Compare any two graphics cards:
GeForce 8800 GT 256MB vs GeForce GTX 580 3GB
IntroThe GeForce 8800 GT 256MB has a core clock frequency of 600 MHz and a GDDR3 memory speed of 700 MHz. It also uses a 256-bit bus, and makes use of a 65 nm design. It features 112 SPUs, 56 TAUs, and 16 ROPs.Compare all of that to the GeForce GTX 580 3GB, which features a clock speed of 772 MHz and a GDDR5 memory speed of 1002 MHz. It also uses a 384-bit memory bus, and uses a 40 nm design. It features 512 SPUs, 64 TAUs, and 48 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 580 3GB, in theory, should be a lot faster than the GeForce 8800 GT 256MB in general. (explain)
Texel RateThe GeForce GTX 580 3GB should be a lot (more or less 47%) faster with regards to AF than the GeForce 8800 GT 256MB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 580 3GB is a better choice, 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 largest amount of information (measured in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
