GeForce 8800 GTS (G80) 640MB vs GeForce 9800 GX2

Intro

The GeForce 8800 GTS (G80) 640MB comes with core speeds of 513 MHz on the GPU, and 792 MHz on the 640 MB of GDDR3 memory. It features 96 SPUs as well as 48 Texture Address Units and 20 ROPs.

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

GeForce 8800 GTS (G80) 640MB 63360 MB/sec
Difference: 64640 (102%)

Texel Rate

The GeForce 9800 GX2 should be quite a bit (more or less 212%) better at anisotropic filtering than the GeForce 8800 GTS (G80) 640MB. (explain)

GeForce 9800 GX2 76800 Mtexels/sec
GeForce 8800 GTS (G80) 640MB 24624 Mtexels/sec
Difference: 52176 (212%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 9800 GX2 is superior to the GeForce 8800 GTS (G80) 640MB, and very much so. (explain)

GeForce 9800 GX2 19200 Mpixels/sec
GeForce 8800 GTS (G80) 640MB 10260 Mpixels/sec
Difference: 8940 (87%)

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 max amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes 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 - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
