GeForce 8600 GT 512MB DDR2 vs GeForce 9600 GSO 384MB

Intro

The GeForce 8600 GT 512MB DDR2 comes with 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 is made up of 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare all of that to the GeForce 9600 GSO 384MB, which features clock speeds of 550 MHz on the GPU, and 800 MHz on the 384 MB of GDDR3 memory. It features 96 SPUs as well as 48 TAUs and 12 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 ability to reach the max fill rate.
