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

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 580 3GB should be 329% faster than the GeForce 8800 GT 256MB overall, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 580 3GB should be much (approximately 47%) better at AF than the GeForce 8800 GT 256MB. (explain)
Pixel RateThe GeForce GTX 580 3GB will be much (more or less 286%) more effective at FSAA than the GeForce 8800 GT 256MB, and also will be able to handle higher screen resolutions without slowing down too much. (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 data (counted in megabytes per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
