GeForce 8800 GTS (G80) 320MB vs GeForce 9600 GSO 512MB

Intro

The GeForce 8800 GTS (G80) 320MB comes with core speeds of 513 MHz on the GPU, and 792 MHz on the 320 MB of GDDR3 memory. It features 96 SPUs as well as 48 TAUs and 20 Rasterization Operator Units.

Compare those specs to the GeForce 9600 GSO 512MB, which has a GPU core clock speed of 650 MHz, and 512 MB of GDDR3 memory running at 900 MHz through a 256-bit bus. It also is comprised of 96 SPUs, 48 TAUs, and 16 ROPs.

As far as performance goes, the GeForce 8800 GTS (G80) 320MB should in theory be a small bit better than the GeForce 9600 GSO 512MB overall. (explain)

GeForce 8800 GTS (G80) 320MB 63360 MB/sec
GeForce 9600 GSO 512MB 57600 MB/sec
Difference: 5760 (10%)

Texel Rate

The GeForce 9600 GSO 512MB will be much (approximately 27%) better at texture filtering than the GeForce 8800 GTS (G80) 320MB. (explain)

GeForce 9600 GSO 512MB 31200 Mtexels/sec
GeForce 8800 GTS (G80) 320MB 24624 Mtexels/sec
Difference: 6576 (27%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 9600 GSO 512MB is the winner, but it probably won't make a huge difference. (explain)

GeForce 9600 GSO 512MB 10400 Mpixels/sec
GeForce 8800 GTS (G80) 320MB 10260 Mpixels/sec
Difference: 140 (1%)

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: Memory bandwidth is the max amount of information (measured in MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. 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 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 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 higher this number, the better the video 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 record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
