Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce RTX 2080 SUPER, in theory, should be a little bit faster than the Geforce GTX 1080 Ti overall. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Geforce GTX 1080 Ti		495616 MB/sec
	Difference: 12288 (2%)

Texel Rate

The Geforce GTX 1080 Ti will be just a bit (more or less 5%) faster with regards to AF than the GeForce RTX 2080 SUPER. (explain)

Geforce GTX 1080 Ti		331520 Mtexels/sec
GeForce RTX 2080 SUPER		316800 Mtexels/sec
	Difference: 14720 (5%)

Pixel Rate

If using high levels of AA is important to you, then the Geforce GTX 1080 Ti is superior to the GeForce RTX 2080 SUPER, and very much so. (explain)

Geforce GTX 1080 Ti		130240 Mpixels/sec
GeForce RTX 2080 SUPER		105600 Mpixels/sec
	Difference: 24640 (23%)

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 max amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video 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 maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units 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 fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
