Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce GTX Titan should in theory be much better than the Radeon R9 M375X overall. (explain)

GeForce GTX Titan		288384 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 216384 (301%)

Texel Rate

The GeForce GTX Titan will be much (about 362%) more effective at AF than the Radeon R9 M375X. (explain)

GeForce GTX Titan		187488 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 146888 (362%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX Titan is the winner, by far. (explain)

GeForce GTX Titan		40176 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 23936 (147%)

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 (counted in MB per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better 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 chip can possibly record to the 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 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 is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
