GeForce 8800 GTS (G80) 640MB vs GeForce 9600 GT 512MB

Intro

The GeForce 8800 GTS (G80) 640MB makes use of a 90 nm design. nVidia has clocked the core speed at 513 MHz. The GDDR3 RAM works at a frequency of 792 MHz on this specific card. It features 96 SPUs along with 48 Texture Address Units and 20 ROPs.

Compare those specs to the GeForce 9600 GT 512MB, which has clock speeds of 650 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 memory. It features 64 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the 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 texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, 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 the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
