Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce GTX Titan X should perform quite a bit faster than the Radeon R9 M375X in general. (explain)

GeForce GTX Titan X		336000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 264000 (367%)

Texel Rate

The GeForce GTX Titan X is a lot (more or less 373%) better at anisotropic filtering than the Radeon R9 M375X. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 151400 (373%)

Pixel Rate

If using lots of anti-aliasing 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
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 79760 (491%)

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 data (measured in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
