Nvidia Titan X vs Radeon RX 480 4GB

Intro

Compare all of that to the Radeon RX 480 4GB, which comes with a clock frequency of 1120 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 256-bit memory bus, and uses a 14 nm design. It is made up of 2304 SPUs, 144 TAUs, and 32 Raster Operation Units.

Radeon RX 480 4GB		150 Watts
Nvidia Titan X		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

Theoretically speaking, the Nvidia Titan X is 114% quicker than the Radeon RX 480 4GB overall, because of its greater bandwidth. (explain)

Nvidia Titan X		491520 MB/sec
Radeon RX 480 4GB		229376 MB/sec
	Difference: 262144 (114%)

Texel Rate

The Nvidia Titan X will be quite a bit (approximately 97%) faster with regards to anisotropic filtering than the Radeon RX 480 4GB. (explain)

Nvidia Titan X		317408 Mtexels/sec
Radeon RX 480 4GB		161280 Mtexels/sec
	Difference: 156128 (97%)

Pixel Rate

If using a high screen resolution is important to you, then the Nvidia Titan X is the winner, and very much so. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon RX 480 4GB		35840 Mpixels/sec
	Difference: 100192 (280%)

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 (counted in megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video 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 maximum amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
