Compare any two graphics cards:
GeForce 8500 GT vs GeForce 8600 GT 1GB DDR2
IntroThe GeForce 8500 GT features a GPU core clock speed of 450 MHz, and the 512 MB of DDR2 memory is set to run at 400 MHz through a 128-bit bus. It also features 16 Stream Processors, 8 Texture Address Units, and 4 ROPs.Compare those specs to the GeForce 8600 GT 1GB DDR2, which makes use of a 80 nm design. nVidia has set the core frequency at 540 MHz. The DDR2 RAM works at a speed of 400 MHz on this card. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same memory bandwidth, so in theory they should perform exactly the same. (explain)
Texel RateThe GeForce 8600 GT 1GB DDR2 should be much (about 140%) more effective at anisotropic filtering than the GeForce 8500 GT. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce 8600 GT 1GB DDR2 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 (counted in MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
