GeForce 8600 GS (OEM) vs GeForce 8600 GT 512MB DDR2
Intro
The GeForce 8600 GS (OEM) features a clock frequency of 540 MHz and a DDR2 memory speed of 400 MHz. It also uses a 128-bit memory bus, and makes use of a 80 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare that to the GeForce 8600 GT 512MB DDR2, which features a GPU core clock speed of 540 MHz, and 512 MB of DDR2 RAM running at 400 MHz through a 128-bit bus. It also is comprised of 32 SPUs, 16 Texture Address Units, and 8 ROPs.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have the exact same bandwidth, so theoretically they should have identical performance. (explain)
Texel Rate
Both cards have exactly the same texel rate, so theoretically they should perform equally good at at anisotropic filtering. (explain)Pixel Rate
Both cards have the exact same pixel rate, so theoretically they should be equally good at at full screen anti-aliasing, 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.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, 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 most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines 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 rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
