GeForce 8600 GS (OEM) vs GeForce 8600 GT 1GB DDR2
Intro
The GeForce 8600 GS (OEM) comes with a GPU core clock speed of 540 MHz, and the 256 MB of DDR2 memory runs at 400 MHz through a 128-bit bus. It also features 32 Stream Processors, 16 Texture Address Units, and 8 ROPs.Compare that to the GeForce 8600 GT 1GB DDR2, which uses a 80 nm design. nVidia has set the core speed at 540 MHz. The DDR2 RAM works at a speed of 400 MHz on this particular model. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have exactly the same memory bandwidth, so in theory they should have identical performance. (explain)
Texel Rate
Both cards have the exact same texel rate, so theoretically they should be equally good at at AF. (explain)Pixel Rate
Both cards have the exact same pixel fill rate, so in theory they should perform equally good at at 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: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 can be processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, 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 the video card could possibly write to its local memory in a 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 - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
