GeForce GTX 1070 Ti vs GeForce GTX 1080

Intro

The GeForce GTX 1070 Ti comes with a core clock frequency of 1607 MHz and a GDDR5 memory speed of 2000 MHz. It also features a 256-bit bus, and makes use of a 16 nm design. It features 2432 SPUs, 152 Texture Address Units, and 64 Raster Operation Units.

Compare all that to the GeForce GTX 1080, which features a clock speed of 1607 MHz and a GDDR5X memory speed of 1251 MHz. It also uses a 256-bit memory bus, and makes use of a 16 nm design. It is made up of 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

GeForce GTX 1080 21942 points
GeForce GTX 1070 Ti 19808 points
Difference: 2134 (11%)

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce GTX 1080 should in theory be much faster than the GeForce GTX 1070 Ti in general. (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 little bit (approximately 5%) faster with regards to 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 the exact same pixel rate, so in theory they should be equally good at at full screen anti-aliasing, 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.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
