Compare any two graphics cards:
GeForce 8800 GT 512MB vs GeForce 8800 GTS (G80) 640MB
IntroThe GeForce 8800 GT 512MB uses a 65 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this card. It features 112 SPUs along with 56 TAUs and 16 Rasterization Operator Units.Compare those specs to the GeForce 8800 GTS (G80) 640MB, which features clock speeds of 513 MHz on the GPU, and 792 MHz on the 640 MB of GDDR3 memory. It features 96 SPUs along with 48 TAUs and 20 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce 8800 GTS (G80) 640MB should perform just a bit faster than the GeForce 8800 GT 512MB in general. (explain)
Texel RateThe GeForce 8800 GT 512MB will be quite a bit (about 36%) better at anisotropic filtering than the GeForce 8800 GTS (G80) 640MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce 8800 GTS (G80) 640MB is a better choice, but not by far. (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 transferred across the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core 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 processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
