Compare any two graphics cards:
GeForce 8500 GT vs GeForce 8600 GS (OEM)
IntroThe GeForce 8500 GT has core clock speeds of 450 MHz on the GPU, and 400 MHz on the 512 MB of DDR2 RAM. It features 16 SPUs as well as 8 TAUs and 4 ROPs.Compare those specifications to the GeForce 8600 GS (OEM), which has a GPU core clock speed of 540 MHz, and 256 MB of DDR2 memory running at 400 MHz through a 128-bit bus. It also is comprised of 32 Stream Processors, 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 have the same performance. (explain)
Texel RateThe GeForce 8600 GS (OEM) should be a lot (about 140%) better at texture filtering than the GeForce 8500 GT. (explain)
Pixel RateThe GeForce 8600 GS (OEM) is much (approximately 140%) better at full screen anti-aliasing than the GeForce 8500 GT, and capable of handling higher screen 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: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card 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 processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
