Compare any two graphics cards:
GeForce 8800 GT 512MB vs GeForce 8800 GTS (G80) 640MB
IntroThe GeForce 8800 GT 512MB makes use of a 65 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 RAM is set to run at a speed of 900 MHz on this specific card. It features 112 SPUs along with 56 TAUs and 16 ROPs.Compare all of that to the GeForce 8800 GTS (G80) 640MB, which has a GPU core clock speed of 513 MHz, and 640 MB of GDDR3 memory running at 792 MHz through a 320-bit bus. It also is comprised of 96 Stream Processors, 48 TAUs, and 20 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 8800 GTS (G80) 640MB should perform a small bit faster than the GeForce 8800 GT 512MB overall. (explain)
Texel RateThe GeForce 8800 GT 512MB is a lot (about 36%) faster with regards to texture filtering than the GeForce 8800 GTS (G80) 640MB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce 8800 GTS (G80) 640MB is superior to the GeForce 8800 GT 512MB, not by a very large margin though. (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 (counted in megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics 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 that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
