GeForce 8600 GT 512MB DDR2 vs GeForce 9600 GSO 768MB

Intro

The GeForce 8600 GT 512MB DDR2 features a GPU core clock speed of 540 MHz, and the 512 MB of DDR2 memory runs at 400 MHz through a 128-bit bus. It also features 32 Stream Processors, 16 TAUs, and 8 ROPs.

Compare those specs to the GeForce 9600 GSO 768MB, which features a GPU core clock speed of 550 MHz, and 768 MB of GDDR3 memory set to run at 800 MHz through a 192-bit bus. It also is made up of 96 Stream Processors, 48 TAUs, and 12 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
