Power Consumption (Max TDP)

Nvidia Titan X		250 Watts
Radeon Vega Frontier Edition		300 Watts
	Difference: 50 Watts (20%)

Memory Bandwidth

Theoretically, the Radeon Vega Frontier Edition should perform a small bit faster than the Nvidia Titan X overall. (explain)

Radeon Vega Frontier Edition		495452 MB/sec
Nvidia Titan X		491520 MB/sec
	Difference: 3932 (1%)

Texel Rate

The Radeon Vega Frontier Edition should be just a bit (about 11%) more effective at anisotropic filtering than the Nvidia Titan X. (explain)

Radeon Vega Frontier Edition		353792 Mtexels/sec
Nvidia Titan X		317408 Mtexels/sec
	Difference: 36384 (11%)

Pixel Rate

The Nvidia Titan X should be much (approximately 54%) more effective at AA than the Radeon Vega Frontier Edition, and able to handle higher resolutions better. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon Vega Frontier Edition		88448 Mpixels/sec
	Difference: 47584 (54%)

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 worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
