Compare any two graphics cards:
GeForce 8600 GT 512MB DDR2 vs GeForce 8800 GTS (G80) 640MB
IntroThe GeForce 8600 GT 512MB DDR2 has a GPU clock speed of 540 MHz, and the 512 MB of DDR2 RAM runs at 400 MHz through a 128-bit bus. It also features 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare those specs to the GeForce 8800 GTS (G80) 640MB, which uses a 90 nm design. nVidia has clocked the core frequency at 513 MHz. The GDDR3 memory is set to run at a frequency of 792 MHz on this particular model. It features 96 SPUs along with 48 Texture Address Units and 20 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 8800 GTS (G80) 640MB should in theory perform a lot faster than the GeForce 8600 GT 512MB DDR2 overall. (explain)
Texel RateThe GeForce 8800 GTS (G80) 640MB will be much (about 185%) faster with regards to texture filtering than the GeForce 8600 GT 512MB DDR2. (explain)
Pixel RateThe GeForce 8800 GTS (G80) 640MB will be much (approximately 138%) faster with regards to anti-aliasing than the GeForce 8600 GT 512MB DDR2, and also should be able to handle higher screen resolutions better. (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 (measured in megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
