GeForce GTX 1080 vs Nvidia Titan X

Intro

Compare that to the Nvidia Titan X, which comes with clock speeds of 1417 MHz on the GPU, and 1251 MHz on the 12288 MB of GDDR5X memory. 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

Theoretically speaking, the Nvidia Titan X should be quite a bit faster than the GeForce GTX 1080 overall. (explain)

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

Texel Rate

The Nvidia Titan X will be much (about 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

The Nvidia Titan X is a lot (about 32%) better at FSAA than the GeForce GTX 1080, and should be able to handle higher screen resolutions without slowing down too much. (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 maximum amount of data (counted in MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
