Compare any two graphics cards:
GeForce 8800 GT 512MB vs GeForce 8800 GTS (G80) 320MB
IntroThe GeForce 8800 GT 512MB uses a 65 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 memory runs at a speed of 900 MHz on this specific card. It features 112 SPUs as well as 56 TAUs and 16 ROPs.Compare that to the GeForce 8800 GTS (G80) 320MB, which has a core clock speed of 513 MHz and a GDDR3 memory speed of 792 MHz. It also makes use of a 320-bit memory bus, and uses a 90 nm design. It is made up of 96 SPUs, 48 Texture Address Units, and 20 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce 8800 GTS (G80) 320MB should theoretically be a small bit superior to the GeForce 8800 GT 512MB overall. (explain)
Texel RateThe GeForce 8800 GT 512MB is a lot (more or less 36%) more effective at texture filtering than the GeForce 8800 GTS (G80) 320MB. (explain)
Pixel RateThe GeForce 8800 GTS (G80) 320MB should be a small bit (approximately 7%) better at anti-aliasing than the GeForce 8800 GT 512MB, and should be able to handle higher 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 max amount of data (measured in MB per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher 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 a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core 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 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 max fill rate.
