Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce GTX 1080 should perform quite a bit faster than the GeForce GTX 1070 Ti overall. (explain)

GeForce GTX 1080		327680 MB/sec
GeForce GTX 1070 Ti		262144 MB/sec
	Difference: 65536 (25%)

Texel Rate

The GeForce GTX 1080 should be a small bit (approximately 5%) better at AF than the GeForce GTX 1070 Ti. (explain)

GeForce GTX 1080		257120 Mtexels/sec
GeForce GTX 1070 Ti		244264 Mtexels/sec
	Difference: 12856 (5%)

Pixel Rate

Both cards have exactly the same pixel rate, so theoretically they should perform equally good at at AA, and be capable of handling the same resolutions. (explain)

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 information (counted in MB per second) that can be moved across the external memory interface in one second. It's 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 DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core 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 applied per second.

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