Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically, the GeForce GTX 1080 should be a lot 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 will be a small bit (approximately 5%) more effective at anisotropic filtering 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 fill rate, so theoretically they should perform equally good at at FSAA, 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 largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
