GeForce 9800 GTX vs GeForce 9800 GX2

Intro

The GeForce 9800 GTX comes with core speeds of 675 MHz on the GPU, and 1100 MHz on the 512 MB of GDDR3 memory. It features 128 SPUs as well as 64 Texture Address Units and 16 ROPs.

Compare those specifications to the GeForce 9800 GX2, which features clock speeds of 600 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR3 memory. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.

Texel Rate

The GeForce 9800 GX2 will be quite a bit (approximately 78%) better at texture filtering than the GeForce 9800 GTX. (explain)

GeForce 9800 GX2 76800 Mtexels/sec
GeForce 9800 GTX 43200 Mtexels/sec
Difference: 33600 (78%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 9800 GX2 is superior to the GeForce 9800 GTX, and very much so. (explain)

GeForce 9800 GX2 19200 Mpixels/sec
GeForce 9800 GTX 10800 Mpixels/sec
Difference: 8400 (78%)

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 data (counted in MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result 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 AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
