Compare any two graphics cards:
GeForce 8500 GT vs GeForce 8600 GS (OEM)
IntroThe GeForce 8500 GT has core speeds of 450 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 memory. It features 16 SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.Compare all of that to the GeForce 8600 GS (OEM), which has a clock frequency of 540 MHz and a DDR2 memory speed of 400 MHz. It also features a 128-bit memory bus, and uses a 80 nm design. It features 32 SPUs, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same bandwidth, so theoretically they should have identical performance. (explain)
Texel RateThe GeForce 8600 GS (OEM) will be a lot (more or less 140%) more effective at anisotropic filtering than the GeForce 8500 GT. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce 8600 GS (OEM) is a better choice, by a large margin. (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 maximum amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 are applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
