Compare any two graphics cards:
GeForce 8600 GS (OEM) vs GeForce 8600 GT 256MB GDDR3
IntroThe GeForce 8600 GS (OEM) comes with a GPU clock speed of 540 MHz, and the 256 MB of DDR2 memory is set to run at 400 MHz through a 128-bit bus. It also features 32 SPUs, 16 Texture Address Units, and 8 ROPs.Compare those specifications to the GeForce 8600 GT 256MB GDDR3, which features core clock speeds of 540 MHz on the GPU, and 700 MHz on the 256 MB of GDDR3 memory. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthAs far as performance goes, the GeForce 8600 GT 256MB GDDR3 should in theory be much better than the GeForce 8600 GS (OEM) overall. (explain)
Texel RateBoth cards have the exact same texel fill rate, so theoretically they should be equally good at at AF. (explain)Pixel RateBoth cards have the exact same pixel rate, so in theory they should perform equally good at at AA, and be able to handle the same resolutions. (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 (measured in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the 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 the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
