GeForce 8600 GTS vs GeForce 9600 GSO 1.5GB

Intro

The GeForce 8600 GTS uses a 80 nm design. nVidia has set the core frequency at 675 MHz. The GDDR3 memory runs at a speed of 1000 MHz on this card. It features 32 SPUs along with 16 Texture Address Units and 8 ROPs.

Compare those specifications to the GeForce 9600 GSO 1.5GB, which comes with GPU core speed of 550 MHz, and 1536 MB of GDDR3 memory running at 800 MHz through a 192-bit bus. It also features 96 SPUs, 48 TAUs, and 12 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 are processed per second. This is worked out by multiplying the total number of texture units of the card by the core clock 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
