GeForce GTX 1080 vs GeForce GTX Titan X

Intro

The GeForce GTX 1080 has a GPU core speed of 1607 MHz, and the 8192 MB of GDDR5X memory runs at 1251 MHz through a 256-bit bus. It also is comprised of 2560 Stream Processors, 160 TAUs, and 64 ROPs.

Compare those specs to the GeForce GTX Titan X, which features a clock speed of 1000 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 384-bit memory bus, and makes use of a 28 nm design. It is comprised of 3072 SPUs, 192 Texture Address Units, and 96 Raster Operation Units.

GeForce GTX Titan X 336000 MB/sec
GeForce GTX 1080 327680 MB/sec
Difference: 8320 (3%)

Texel Rate

The GeForce GTX 1080 should be quite a bit (more or less 34%) better at texture filtering than the GeForce GTX Titan X. (explain)

GeForce GTX 1080 257120 Mtexels/sec
GeForce GTX Titan X 192000 Mtexels/sec
Difference: 65120 (34%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 1080 is superior to the GeForce GTX Titan X, but only just. (explain)

GeForce GTX 1080 102848 Mpixels/sec
GeForce GTX Titan X 96000 Mpixels/sec
Difference: 6848 (7%)

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: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
