Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

As far as performance goes, the Geforce GTX 1080 Ti should in theory be a lot superior to the Radeon HD 7970 in general. (explain)

Geforce GTX 1080 Ti		495616 MB/sec
Radeon HD 7970		264000 MB/sec
	Difference: 231616 (88%)

Texel Rate

The Geforce GTX 1080 Ti should be quite a bit (approximately 180%) faster with regards to texture filtering than the Radeon HD 7970. (explain)

Geforce GTX 1080 Ti		331520 Mtexels/sec
Radeon HD 7970		118400 Mtexels/sec
	Difference: 213120 (180%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Geforce GTX 1080 Ti is superior to the Radeon HD 7970, and very much so. (explain)

Geforce GTX 1080 Ti		130240 Mpixels/sec
Radeon HD 7970		29600 Mpixels/sec
	Difference: 100640 (340%)

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 (measured in MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output 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 ability to reach the max fill rate.
