GeForce GTX 1080 vs Radeon RX 5700 XT

Intro

Compare those specifications to the Radeon RX 5700 XT, which has GPU clock speed of 1605 MHz, and 8096 MB of GDDR6 RAM running at 1750 MHz through a 256-bit bus. It also is comprised of 2560 Stream Processors, 160 TAUs, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

The Radeon RX 5700 XT should in theory perform much faster than the GeForce GTX 1080 in general. (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 (about 0%) faster with regards to anisotropic 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 running with lots of anti-aliasing is important to you, then the GeForce GTX 1080 is superior to the Radeon RX 5700 XT, 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 largest amount of data (counted in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum number 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock 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 also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
