GeForce 9800 GX2 vs GeForce GTX 1070 Ti

Intro

Compare those specifications to the GeForce GTX 1070 Ti, which comes with a GPU core clock speed of 1607 MHz, and 8192 MB of GDDR5 RAM running at 2000 MHz through a 256-bit bus. It also is made up of 2432 Stream Processors, 152 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1070 Ti		180 Watts
GeForce 9800 GX2		197 Watts
	Difference: 17 Watts (9%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1070 Ti should perform quite a bit faster than the GeForce 9800 GX2 in general. (explain)

GeForce GTX 1070 Ti		262144 MB/sec
GeForce 9800 GX2		128000 MB/sec
	Difference: 134144 (105%)

Texel Rate

The GeForce GTX 1070 Ti should be quite a bit (more or less 218%) better at anisotropic filtering than the GeForce 9800 GX2. (explain)

GeForce GTX 1070 Ti		244264 Mtexels/sec
GeForce 9800 GX2		76800 Mtexels/sec
	Difference: 167464 (218%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 1070 Ti is superior to the GeForce 9800 GX2, and very much so. (explain)

GeForce GTX 1070 Ti		102848 Mpixels/sec
GeForce 9800 GX2		19200 Mpixels/sec
	Difference: 83648 (436%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
