GeForce 8600 GTS vs GeForce 9600 GSO 1.5GB

Intro

The GeForce 8600 GTS features a GPU core clock speed of 675 MHz, and the 512 MB of GDDR3 memory runs at 1000 MHz through a 128-bit bus. It also features 32 SPUs, 16 TAUs, and 8 ROPs.

Compare those specs to the GeForce 9600 GSO 1.5GB, which uses a 65 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR3 RAM works at a frequency of 800 MHz on this specific card. It features 96 SPUs along with 48 TAUs and 12 ROPs.

GeForce 9600 GSO 1.5GB 38400 MB/sec
GeForce 8600 GTS 32000 MB/sec
Difference: 6400 (20%)

Texel Rate

The GeForce 9600 GSO 1.5GB will be much (more or less 144%) better at anisotropic filtering than the GeForce 8600 GTS. (explain)

GeForce 9600 GSO 1.5GB 26400 Mtexels/sec
GeForce 8600 GTS 10800 Mtexels/sec
Difference: 15600 (144%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 9600 GSO 1.5GB is superior to the GeForce 8600 GTS, by a large margin. (explain)

GeForce 9600 GSO 1.5GB 6600 Mpixels/sec
GeForce 8600 GTS 5400 Mpixels/sec
Difference: 1200 (22%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
