GeForce 8600 GS (OEM) vs GeForce 9800 GT 1GB
Intro
The GeForce 8600 GS (OEM) features a core clock frequency of 540 MHz and a DDR2 memory frequency of 400 MHz. It also features a 128-bit bus, and uses a 80 nm design. It is made up of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare those specs to the GeForce 9800 GT 1GB, which has GPU core speed of 600 MHz, and 1024 MB of GDDR3 RAM running at 900 MHz through a 256-bit bus. It also features 112 Stream Processors, 56 TAUs, and 16 ROPs.

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