GeForce 8800 GTS (G80) 640MB vs GeForce 9600 GSO 512MB

Intro

The GeForce 8800 GTS (G80) 640MB has a GPU core speed of 513 MHz, and the 640 MB of GDDR3 memory runs at 792 MHz through a 320-bit bus. It also is made up of 96 SPUs, 48 Texture Address Units, and 20 ROPs.

Compare that to the GeForce 9600 GSO 512MB, which has a clock speed of 650 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 256-bit bus, and makes use of a 65/55 nm design. It features 96 SPUs, 48 Texture Address Units, and 16 ROPs.

GeForce 9600 GSO 512MB 90 Watts
GeForce 8800 GTS (G80) 640MB 143 Watts
Difference: 53 Watts (59%)

Memory Bandwidth

The GeForce 8800 GTS (G80) 640MB should in theory be a little bit faster than the GeForce 9600 GSO 512MB in general. (explain)

GeForce 8800 GTS (G80) 640MB 63360 MB/sec
GeForce 9600 GSO 512MB 57600 MB/sec
Difference: 5760 (10%)

Texel Rate

The GeForce 9600 GSO 512MB is quite a bit (about 27%) more effective at texture filtering than the GeForce 8800 GTS (G80) 640MB. (explain)

GeForce 9600 GSO 512MB 31200 Mtexels/sec
GeForce 8800 GTS (G80) 640MB 24624 Mtexels/sec
Difference: 6576 (27%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 9600 GSO 512MB is a better choice, but not by far. (explain)

GeForce 9600 GSO 512MB 10400 Mpixels/sec
GeForce 8800 GTS (G80) 640MB 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 moved past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
