GeForce GTX 1070 Ti vs GeForce GTX 1080

Intro

Compare all that to the GeForce GTX 1080, which comes with GPU clock speed of 1607 MHz, and 8192 MB of GDDR5X RAM running at 1251 MHz through a 256-bit bus. It also features 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce GTX 1080 should in theory perform much 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 is a small bit (approximately 5%) faster with regards to 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 the exact same pixel fill rate, so in theory they should be equally good at at AA, and be able to handle the same screen 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 (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, 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 number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 potential to reach the max fill rate.
