Nvidia Titan X vs Radeon R7 250X

Intro

Compare all of that to the Radeon R7 250X, which has a GPU core clock speed of 1000 MHz, and 1024 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Radeon R7 250X		95 Watts
Nvidia Titan X		250 Watts
	Difference: 155 Watts (163%)

Memory Bandwidth

In theory, the Nvidia Titan X is 583% faster than the Radeon R7 250X overall, because of its greater bandwidth. (explain)

Nvidia Titan X		491520 MB/sec
Radeon R7 250X		72000 MB/sec
	Difference: 419520 (583%)

Texel Rate

The Nvidia Titan X is a lot (approximately 694%) better at anisotropic filtering than the Radeon R7 250X. (explain)

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

Pixel Rate

The Nvidia Titan X should be much (more or less 750%) better at anti-aliasing than the Radeon R7 250X, and also capable of handling higher screen resolutions better. (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 maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
