GeForce 8600 GS (OEM) vs GeForce 8600 GT 1GB DDR2
Intro
The GeForce 8600 GS (OEM) has a clock speed of 540 MHz and a DDR2 memory frequency of 400 MHz. It also makes use of 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 all of that to the GeForce 8600 GT 1GB DDR2, which features core clock speeds of 540 MHz on the GPU, and 400 MHz on the 1024 MB of DDR2 RAM. It features 32 SPUs along with 16 TAUs and 8 ROPs.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have exactly the same bandwidth, so in theory they should perform exactly the same. (explain)
Texel Rate
Both cards have the exact same texel fill rate, so in theory they should perform equally good at at anisotropic filtering. (explain)Pixel Rate
Both cards have the exact same pixel rate, so in theory 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: Memory bandwidth is the largest amount of data (in units of MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling 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 graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
