GeForce GTX 1080 vs Radeon RX 5700 XT

Intro

Compare that to the Radeon RX 5700 XT, which features a core clock speed of 1605 MHz and a GDDR6 memory frequency of 1750 MHz. It also features a 256-bit bus, and uses a 7 nm design. It is made up of 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

GeForce GTX 1080		180 Watts
Radeon RX 5700 XT		225 Watts
	Difference: 45 Watts (25%)

Memory Bandwidth

Theoretically, the Radeon RX 5700 XT should perform much faster than the GeForce GTX 1080 overall. (explain)

Radeon RX 5700 XT		458752 MB/sec
GeForce GTX 1080		327680 MB/sec
	Difference: 131072 (40%)

Texel Rate

The GeForce GTX 1080 is a small bit (more or less 0%) more effective at texture filtering than the Radeon RX 5700 XT. (explain)

GeForce GTX 1080		257120 Mtexels/sec
Radeon RX 5700 XT		256800 Mtexels/sec
	Difference: 320 (0%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 1080 is the winner, though not by far. (explain)

GeForce GTX 1080		102848 Mpixels/sec
Radeon RX 5700 XT		102720 Mpixels/sec
	Difference: 128 (0%)

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 (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
