GeForce GTX 1080 vs Nvidia Titan X

Intro

Compare all that to the Nvidia Titan X, which features a core clock speed of 1417 MHz and a GDDR5X memory speed of 1251 MHz. It also makes use of a 384-bit memory bus, and uses a 16 nm design. It is made up of 3584 SPUs, 224 TAUs, and 96 ROPs.

Power Consumption (Max TDP)

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

Memory Bandwidth

Performance-wise, the Nvidia Titan X should theoretically be a lot better 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 (more or less 23%) better at anisotropic 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 running with lots of anti-aliasing is important to you, then the Nvidia Titan X is superior to the GeForce GTX 1080, by far. (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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
