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

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have exactly the same memory bandwidth, so in theory they should have identical performance. (explain)
Texel RateThe GeForce 8600 GT 512MB DDR2 should be quite a bit (more or less 140%) faster with regards to texture filtering than the GeForce 8500 GT. (explain)
Pixel RateThe GeForce 8600 GT 512MB DDR2 will be a lot (about 140%) more effective at FSAA than the GeForce 8500 GT, and also should be able to handle higher 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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses 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, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
