Nvidia Titan X vs Radeon R9 270X

Intro

Compare that to the Radeon R9 270X, which comes with clock speeds of 1000 MHz on the GPU, and 1400 MHz on the 2048 MB of GDDR5 memory. It features 1280 SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.

Radeon R9 270X		180 Watts
Nvidia Titan X		250 Watts
	Difference: 70 Watts (39%)

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X will be 174% quicker than the Radeon R9 270X in general, due to its higher bandwidth. (explain)

Nvidia Titan X		491520 MB/sec
Radeon R9 270X		179200 MB/sec
	Difference: 312320 (174%)

Texel Rate

The Nvidia Titan X should be a lot (about 297%) more effective at AF than the Radeon R9 270X. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon R9 270X		80000 Mtexels/sec
	Difference: 237408 (297%)

Pixel Rate

If using high levels of AA is important to you, then the Nvidia Titan X is a better choice, and very much so. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon R9 270X		32000 Mpixels/sec
	Difference: 104032 (325%)

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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
