GeForce 8800 GT 512MB vs GeForce 9600 GSO 768MB

Intro

The GeForce 8800 GT 512MB has a GPU core clock speed of 600 MHz, and the 512 MB of GDDR3 memory runs at 900 MHz through a 256-bit bus. It also is made up of 112 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Compare all that to the GeForce 9600 GSO 768MB, which uses a 65 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR3 memory works at a speed of 800 MHz on this specific card. It features 96 SPUs as well as 48 Texture Address Units and 12 Rasterization Operator Units.

GeForce 9600 GSO 768MB 38400 MB/sec
Difference: 19200 (50%)

Texel Rate

The GeForce 8800 GT 512MB is a lot (approximately 27%) better at anisotropic filtering than the GeForce 9600 GSO 768MB. (explain)

GeForce 8800 GT 512MB 33600 Mtexels/sec
GeForce 9600 GSO 768MB 26400 Mtexels/sec
Difference: 7200 (27%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 8800 GT 512MB is superior to the GeForce 9600 GSO 768MB, by far. (explain)

GeForce 8800 GT 512MB 9600 Mpixels/sec
GeForce 9600 GSO 768MB 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: Bandwidth is the largest amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once 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 anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
