GeForce GTX 980 Ti		336000 MB/sec
	Difference: 294784 (88%)

Texel Rate

The GeForce RTX 2080 Ti should be quite a bit (approximately 109%) faster with regards to AF than the GeForce GTX 980 Ti. (explain)

GeForce RTX 2080 Ti		367200 Mtexels/sec
GeForce GTX 980 Ti		176000 Mtexels/sec
	Difference: 191200 (109%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 2080 Ti is the winner, by far. (explain)

GeForce RTX 2080 Ti		118800 Mpixels/sec
GeForce GTX 980 Ti		96000 Mpixels/sec
	Difference: 22800 (24%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's 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 output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
