Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X is 583% faster than the Radeon R9 M375X in general, due to its greater bandwidth. (explain)

Nvidia Titan X		491520 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 419520 (583%)

Texel Rate

The Nvidia Titan X should be much (approximately 682%) faster with regards to anisotropic filtering than the Radeon R9 M375X. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 276808 (682%)

Pixel Rate

If running with a high resolution is important to you, then the Nvidia Titan X is the winner, by far. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 119792 (738%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
