GeForce 8600 GS (OEM) vs GeForce GT 450 (OEM)
Intro
The GeForce 8600 GS (OEM) makes use of a 80 nm design. nVidia has set the core frequency at 540 MHz. The DDR2 RAM works at a speed of 400 MHz on this particular card. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.Compare all of that to the GeForce GT 450 (OEM), which comes with GPU clock speed of 790 MHz, and 1536 MB of GDDR5 RAM running at 1000 MHz through a 192-bit bus. It also is made up of 144 Stream Processors, 24 Texture Address Units, and 24 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
