GeForce 9800 GX2 vs GeForce GTX 1070 Ti

Intro

Compare all of that to the GeForce GTX 1070 Ti, which has a core clock speed of 1607 MHz and a GDDR5 memory speed of 2000 MHz. It also features a 256-bit bus, and makes use of a 16 nm design. It is comprised of 2432 SPUs, 152 TAUs, and 64 Raster Operation Units.

GeForce 9800 GX2		128000 MB/sec
	Difference: 134144 (105%)

Texel Rate

The GeForce GTX 1070 Ti should be much (about 218%) more effective at AF 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 a high resolution is important to you, then the GeForce GTX 1070 Ti is a better choice, 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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
