Nvidia Titan X vs Radeon RX 480

Intro

Compare those specs to the Radeon RX 480, which features GPU core speed of 1120 MHz, and 8192 MB of GDDR5 memory set to run at 2000 MHz through a 256-bit bus. It also is comprised of 2304 Stream Processors, 144 Texture Address Units, and 32 ROPs.

The Nvidia Titan X should in theory be a lot faster than the Radeon RX 480 overall. (explain)

Nvidia Titan X		491520 MB/sec
Radeon RX 480		262144 MB/sec
	Difference: 229376 (88%)

Texel Rate

The Nvidia Titan X will be much (more or less 97%) faster with regards to texture filtering than the Radeon RX 480. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the Nvidia Titan X is superior to the Radeon RX 480, by far. (explain)

Nvidia Titan X		136032 Mpixels/sec
Radeon RX 480		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 information (in units of megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
