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

Intro

The GeForce 8800 GTS (G80) 640MB features a GPU core speed of 513 MHz, and the 640 MB of GDDR3 RAM is set to run at 792 MHz through a 320-bit bus. It also is comprised of 96 SPUs, 48 Texture Address Units, and 20 Raster Operation Units.

Compare all of that to the GeForce 9800 GX2, which comes with a GPU core clock speed of 600 MHz, and 512 MB of GDDR3 RAM set to run at 1000 MHz through a 256-bit bus. It also features 128 Stream Processors, 64 TAUs, and 16 ROPs.

Difference: 52176 (212%)

Pixel Rate

The GeForce 9800 GX2 will be a lot (approximately 87%) more effective at FSAA than the GeForce 8800 GTS (G80) 640MB, and also should be able to handle higher resolutions better. (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 data (measured in MB per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has 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 AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
