GeForce GTX 1080 vs Nvidia Titan X

Intro

Compare those specifications to the Nvidia Titan X, which makes use of a 16 nm design. nVidia has clocked the core frequency at 1417 MHz. The GDDR5X RAM works at a frequency of 1251 MHz on this particular model. It features 3584 SPUs as well as 224 TAUs and 96 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1080		180 Watts
Nvidia Titan X		250 Watts
	Difference: 70 Watts (39%)

Memory Bandwidth

In theory, the Nvidia Titan X should be 50% quicker than the GeForce GTX 1080 in general, because of its higher data rate. (explain)

Nvidia Titan X		491520 MB/sec
GeForce GTX 1080		327680 MB/sec
	Difference: 163840 (50%)

Texel Rate

The Nvidia Titan X is quite a bit (more or less 23%) more effective at texture filtering than the GeForce GTX 1080. (explain)

Nvidia Titan X		317408 Mtexels/sec
GeForce GTX 1080		257120 Mtexels/sec
	Difference: 60288 (23%)

Pixel Rate

If using a high resolution is important to you, then the Nvidia Titan X is a better choice, by a large margin. (explain)

Nvidia Titan X		136032 Mpixels/sec
GeForce GTX 1080		102848 Mpixels/sec
	Difference: 33184 (32%)

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 data (in units of MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, the result should 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
