GeForce 8600 GTS vs GeForce 9600 GSO 384MB

Intro

The GeForce 8600 GTS uses a 80 nm design. nVidia has set the core frequency at 675 MHz. The GDDR3 RAM runs at a frequency of 1000 MHz on this specific card. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Compare those specs to the GeForce 9600 GSO 384MB, which uses a 65 nm design. nVidia has set the core frequency at 550 MHz. The GDDR3 RAM is set to run at a speed of 800 MHz on this particular model. It features 96 SPUs along with 48 TAUs and 12 ROPs.

GeForce 9600 GSO 384MB 38400 MB/sec
GeForce 8600 GTS 32000 MB/sec
Difference: 6400 (20%)

Texel Rate

The GeForce 9600 GSO 384MB will be quite a bit (about 144%) better at texture filtering than the GeForce 8600 GTS. (explain)

GeForce 9600 GSO 384MB 26400 Mtexels/sec
GeForce 8600 GTS 10800 Mtexels/sec
Difference: 15600 (144%)

Pixel Rate

The GeForce 9600 GSO 384MB is quite a bit (more or less 22%) more effective at AA than the GeForce 8600 GTS, and also should be capable of handling higher resolutions while still performing well. (explain)

GeForce 9600 GSO 384MB 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 (in units of megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
