GeForce GTX 1080 vs Radeon RX 5600 XT

Intro

Compare those specifications to the Radeon RX 5600 XT, which has a GPU core clock speed of 1375 MHz, and 6144 MB of GDDR6 RAM running at 1500 MHz through a 192-bit bus. It also is made up of 2304 Stream Processors, 144 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600 XT		160 Watts
GeForce GTX 1080		180 Watts
	Difference: 20 Watts (13%)

Memory Bandwidth

Performance-wise, the Radeon RX 5600 XT should in theory be just a bit superior to the GeForce GTX 1080 overall. (explain)

Radeon RX 5600 XT		344064 MB/sec
GeForce GTX 1080		327680 MB/sec
	Difference: 16384 (5%)

Texel Rate

The GeForce GTX 1080 is a lot (about 30%) faster with regards to AF than the Radeon RX 5600 XT. (explain)

GeForce GTX 1080		257120 Mtexels/sec
Radeon RX 5600 XT		198000 Mtexels/sec
	Difference: 59120 (30%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1080 is a better choice, though only just barely. (explain)

GeForce GTX 1080		102848 Mpixels/sec
Radeon RX 5600 XT		88000 Mpixels/sec
	Difference: 14848 (17%)

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 (measured in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR memory, the result should 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
