GeForce GTX 1070 Ti vs GeForce GTX 1080

Intro

Compare all of that to the GeForce GTX 1080, which features a core clock speed of 1607 MHz and a GDDR5X memory frequency of 1251 MHz. It also makes use of a 256-bit memory bus, and uses a 16 nm design. It features 2560 SPUs, 160 TAUs, 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 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 is a small bit (more or less 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 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: Memory bandwidth is the max amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip 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 ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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 max fill rate.
