Compare any two graphics cards:
GeForce GTX 480 vs GeForce GTX 580
IntroThe GeForce GTX 480 features a core clock speed of 700 MHz and a GDDR5 memory speed of 924 MHz. It also features a 384-bit memory bus, and makes use of a 40 nm design. It features 480 SPUs, 60 Texture Address Units, and 48 ROPs.
Compare those specifications to the GeForce GTX 580, which comes with a GPU core clock speed of 772 MHz, and 1536 MB of GDDR5 RAM set to run at 1002 MHz through a 384-bit bus. It also is comprised of 512 SPUs, 64 Texture Address Units, and 48 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 580 is 8% faster than the GeForce GTX 480 in general, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTX 580 will be a bit (more or less 18%) faster with regards to anisotropic filtering than the GeForce GTX 480. (explain)
Pixel RateThe GeForce GTX 580 is just a bit (approximately 10%) faster with regards to full screen anti-aliasing than the GeForce GTX 480, and also will be capable of handling 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.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 can be processed per second. This is worked out by multiplying the total number of texture units 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 in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's 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 rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
