Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Performance-wise, the GeForce RTX 2080 SUPER should in theory be quite a bit better than the GeForce GTX 780 Ti in general. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
GeForce GTX 780 Ti		336000 MB/sec
	Difference: 171904 (51%)

Texel Rate

The GeForce RTX 2080 SUPER is a lot (about 51%) faster with regards to anisotropic filtering than the GeForce GTX 780 Ti. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
GeForce GTX 780 Ti		210000 Mtexels/sec
	Difference: 106800 (51%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 2080 SUPER is the winner, by a large margin. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
GeForce GTX 780 Ti		42000 Mpixels/sec
	Difference: 63600 (151%)

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 maximum amount of data (counted in MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, the result 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 anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels 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 number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
