Geforce GTX 1080 Ti vs Nvidia Titan X

Intro

Compare those specs to the Nvidia Titan X, which comes with GPU core speed of 1417 MHz, and 12288 MB of GDDR5X RAM running at 1251 MHz through a 384-bit bus. It also is comprised of 3584 Stream Processors, 224 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the Geforce GTX 1080 Ti is 1% quicker than the Nvidia Titan X overall, due to its higher bandwidth. (explain)

Geforce GTX 1080 Ti		495616 MB/sec
Nvidia Titan X		491520 MB/sec
	Difference: 4096 (1%)

Texel Rate

The Geforce GTX 1080 Ti will be a small bit (approximately 4%) better at anisotropic filtering than the Nvidia Titan X. (explain)

Geforce GTX 1080 Ti		331520 Mtexels/sec
Nvidia Titan X		317408 Mtexels/sec
	Difference: 14112 (4%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Nvidia Titan X is superior to the Geforce GTX 1080 Ti, though only just barely. (explain)

Nvidia Titan X		136032 Mpixels/sec
Geforce GTX 1080 Ti		130240 Mpixels/sec
	Difference: 5792 (4%)

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 largest amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the 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 that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour 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 reach the maximum fill rate.
