Compare any two graphics cards:
GeForce GTX 480 vs GeForce GTX 580
IntroThe GeForce GTX 480 makes use of a 40 nm design. nVidia has set the core speed at 700 MHz. The GDDR5 RAM works at a frequency of 924 MHz on this model. It features 480 SPUs as well as 60 Texture Address Units and 48 Rasterization Operator Units.
Compare all of that to the GeForce GTX 580, which has a GPU core clock speed of 772 MHz, and 1536 MB of GDDR5 RAM running at 1002 MHz through a 384-bit bus. It also features 512 SPUs, 64 Texture Address Units, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the GeForce GTX 580 should be a little bit faster than the GeForce GTX 480 overall. (explain)
Texel RateThe GeForce GTX 580 should be a bit (approximately 18%) better at texture filtering than the GeForce GTX 480. (explain)
Pixel RateThe GeForce GTX 580 is a small bit (approximately 10%) better at AA than the GeForce GTX 480, and should be able to handle 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.

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 processed per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
