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

Intro

The GeForce 8800 GTS (G80) 320MB makes use of a 90 nm design. nVidia has clocked the core frequency at 513 MHz. The GDDR3 RAM is set to run at a frequency of 792 MHz on this particular model. It features 96 SPUs along with 48 TAUs and 20 ROPs.

Compare those specifications to the GeForce 9600 GSO 512MB, which comes with a GPU core clock speed of 650 MHz, and 512 MB of GDDR3 memory set to run at 900 MHz through a 256-bit bus. It also is made up of 96 Stream Processors, 48 TAUs, and 16 Raster Operation Units.

Difference: 53 Watts (59%)

Memory Bandwidth

As far as performance goes, the GeForce 8800 GTS (G80) 320MB should in theory be a small bit superior to the GeForce 9600 GSO 512MB in general. (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 should be a lot (about 27%) more effective 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 high levels of AA is important to you, then the GeForce 9600 GSO 512MB is a better choice, though only just barely. (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: Bandwidth is the max amount of information (counted in megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
