GeForce 8600 GS (OEM) vs GeForce 8600 GT 256MB DDR2
Intro
The GeForce 8600 GS (OEM) comes with a GPU core 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 is made up of 32 Stream Processors, 16 TAUs, and 8 ROPs.Compare all of that to the GeForce 8600 GT 256MB DDR2, which features a core clock frequency of 540 MHz and a DDR2 memory speed of 400 MHz. It also makes use of a 128-bit memory bus, and makes use of a 80 nm design. It features 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have exactly the same memory bandwidth, so theoretically they should perform exactly the same. (explain)
Texel Rate
Both cards have the exact same texel fill rate, so theoretically they should be equally good at at anisotropic filtering. (explain)Pixel Rate
Both cards have exactly the same pixel rate, so theoretically they should be 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.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total 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 handling 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 the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
