Compare any two graphics cards:
GeForce 8800 GT 256MB vs GeForce 9600 GSO 384MB
IntroThe GeForce 8800 GT 256MB uses a 65 nm design. nVidia has set the core speed at 600 MHz. The GDDR3 memory runs at a frequency of 700 MHz on this particular model. It features 112 SPUs along with 56 Texture Address Units and 16 ROPs.Compare all that to the GeForce 9600 GSO 384MB, which features GPU core speed of 550 MHz, and 384 MB of GDDR3 RAM running at 800 MHz through a 192-bit bus. It also features 96 SPUs, 48 Texture Address Units, and 12 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce 8800 GT 256MB should be a bit faster than the GeForce 9600 GSO 384MB overall. (explain)
Texel RateThe GeForce 8800 GT 256MB will be much (more or less 27%) more effective at anisotropic filtering than the GeForce 9600 GSO 384MB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce 8800 GT 256MB is the winner, and very much so. (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 maximum amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at 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 that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
