Nvidia Titan X vs Radeon R7 250X

Intro

Compare all of that to the Radeon R7 250X, which makes use of a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this specific model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X should be 583% faster than the Radeon R7 250X overall, because of its higher bandwidth. (explain)

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

Texel Rate

The Nvidia Titan X will be quite a bit (about 694%) more effective 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 is quite a bit (about 750%) more effective at anti-aliasing than the Radeon R7 250X, and will be able to handle higher screen resolutions without slowing down too much. (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 max amount of information (counted in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core 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 fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
