GeForce 8600 GT 512MB DDR2 vs GeForce 9600 GSO 1.5GB

Intro

The GeForce 8600 GT 512MB DDR2 has a clock speed of 540 MHz and a DDR2 memory frequency of 400 MHz. It also uses a 128-bit bus, and uses a 80 nm design. It features 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare those specifications to the GeForce 9600 GSO 1.5GB, which has core clock speeds of 550 MHz on the GPU, and 800 MHz on the 1536 MB of GDDR3 memory. It features 96 SPUs as well as 48 Texture Address Units and 12 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
