GeForce 9500 GT DDR2 vs GeForce 9600 GSO 384MB

Intro

The GeForce 9500 GT DDR2 makes use of a 65 nm design. nVidia has clocked the core speed at 550 MHz. The DDR2 memory works at a speed of 500 MHz on this particular card. It features 32 SPUs along with 16 TAUs and 8 Rasterization Operator Units.

Compare that to the GeForce 9600 GSO 384MB, which features a clock frequency of 550 MHz and a GDDR3 memory speed of 800 MHz. It also uses a 192-bit bus, and makes use of a 65 nm design. It is comprised of 96 SPUs, 48 TAUs, and 12 ROPs.

GeForce 9500 GT DDR2 50 Watts
GeForce 9600 GSO 384MB 84 Watts
Difference: 34 Watts (68%)

Memory Bandwidth

Theoretically speaking, the GeForce 9600 GSO 384MB should be quite a bit faster than the GeForce 9500 GT DDR2 in general. (explain)

GeForce 9600 GSO 384MB 38400 MB/sec
GeForce 9500 GT DDR2 16000 MB/sec
Difference: 22400 (140%)

Texel Rate

The GeForce 9600 GSO 384MB is much (about 200%) better at anisotropic filtering than the GeForce 9500 GT DDR2. (explain)

GeForce 9600 GSO 384MB 26400 Mtexels/sec
GeForce 9500 GT DDR2 8800 Mtexels/sec
Difference: 17600 (200%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 9600 GSO 384MB is the winner, and very much so. (explain)

GeForce 9600 GSO 384MB 6600 Mpixels/sec
GeForce 9500 GT DDR2 4400 Mpixels/sec
Difference: 2200 (50%)

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 moved across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
