Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce GTX Titan X should be 17% faster than the GeForce GTX Titan overall, due to its greater data rate. (explain)

GeForce GTX Titan X		336000 MB/sec
GeForce GTX Titan		288384 MB/sec
	Difference: 47616 (17%)

Texel Rate

The GeForce GTX Titan X should be a little bit (more or less 2%) more effective at texture filtering than the GeForce GTX Titan. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
GeForce GTX Titan		187488 Mtexels/sec
	Difference: 4512 (2%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX Titan X is the winner, by a large margin. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
GeForce GTX Titan		40176 Mpixels/sec
	Difference: 55824 (139%)

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 information (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed 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 video 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 that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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 memory bandwidth is, the lower the potential to reach the max fill rate.
