GeForce GTX 1070 Ti		262144 MB/sec
	Difference: 196608 (75%)

Texel Rate

The GeForce RTX 2080 will be a little bit (about 14%) better at anisotropic filtering than the GeForce GTX 1070 Ti. (explain)

GeForce RTX 2080		278760 Mtexels/sec
GeForce GTX 1070 Ti		244264 Mtexels/sec
	Difference: 34496 (14%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1070 Ti is the winner, not by a very large margin though. (explain)

GeForce GTX 1070 Ti		102848 Mpixels/sec
GeForce RTX 2080		96960 Mpixels/sec
	Difference: 5888 (6%)

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: Bandwidth is the largest amount of information (measured in MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units by the core clock 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in a 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 - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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.
