GeForce 9600 GSO 768MB vs GeForce 9800 GX2

Intro

The GeForce 9600 GSO 768MB features core clock speeds of 550 MHz on the GPU, and 800 MHz on the 768 MB of GDDR3 memory. It features 96 SPUs as well as 48 TAUs and 12 ROPs.

Compare those specifications to the GeForce 9800 GX2, which comes with a clock speed of 600 MHz and a GDDR3 memory frequency of 1000 MHz. It also makes use of a 256-bit bus, and uses a 65 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 9800 GX2 is a better choice, by a large margin. (explain)

GeForce 9800 GX2 19200 Mpixels/sec
GeForce 9600 GSO 768MB 6600 Mpixels/sec
Difference: 12600 (191%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few 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.
