Theoretically speaking, the GeForce 8800 GT 256MB should be 17% faster than the GeForce 9600 GSO 384MB overall, because of its greater bandwidth. (explain)

GeForce 8800 GT 256MB 44800 MB/sec
GeForce 9600 GSO 384MB 38400 MB/sec
Difference: 6400 (17%)

Texel Rate

The GeForce 8800 GT 256MB is much (more or less 27%) more effective at texture filtering than the GeForce 9600 GSO 384MB. (explain)

GeForce 8800 GT 256MB 33600 Mtexels/sec
GeForce 9600 GSO 384MB 26400 Mtexels/sec
Difference: 7200 (27%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 8800 GT 256MB is a better choice, by far. (explain)

GeForce 8800 GT 256MB 9600 Mpixels/sec
GeForce 9600 GSO 384MB 6600 Mpixels/sec
Difference: 3000 (45%)

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 data (counted in MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling 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 the video card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
