Compare any two graphics cards:
GeForce 8500 GT vs GeForce 8600 GT 1GB DDR2
IntroThe GeForce 8500 GT uses a 80 nm design. nVidia has clocked the core frequency at 450 MHz. The DDR2 memory is set to run at a frequency of 400 MHz on this particular card. It features 16 SPUs along with 8 Texture Address Units and 4 ROPs.Compare those specifications to the GeForce 8600 GT 1GB DDR2, which uses a 80 nm design. nVidia has set the core speed at 540 MHz. The DDR2 memory is set to run at a speed of 400 MHz on this model. It features 32 SPUs along with 16 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have exactly the same bandwidth, so in theory they should perform the same. (explain)
Texel RateThe GeForce 8600 GT 1GB DDR2 will be a lot (more or less 140%) more effective at anisotropic filtering than the GeForce 8500 GT. (explain)
Pixel RateThe GeForce 8600 GT 1GB DDR2 is much (about 140%) better at anti-aliasing than the GeForce 8500 GT, and will be capable of handling higher resolutions while still performing well. (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 (in units of megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once 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 amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
