Radeon R7 250X		72000 MB/sec
	Difference: 419520 (583%)

Texel Rate

The Nvidia Titan X is a lot (more or less 694%) faster with regards to texture filtering than the Radeon R7 250X. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 277408 (694%)

Pixel Rate

If using high levels of AA is important to you, then the Nvidia Titan X is the winner, by a large margin. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon R7 250X		16000 Mpixels/sec
	Difference: 120032 (750%)

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 (measured in MB per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock 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 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 potential to reach the maximum fill rate.
