GeForce 8600 GT 512MB DDR2 vs GeForce 8800 GT 512MB

Intro

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

Compare those specifications to the GeForce 8800 GT 512MB, which uses a 65 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 memory works at a frequency of 900 MHz on this specific card. It features 112 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result 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 anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling 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 that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
