GeForce GTX 1080 vs Radeon RX 5600 XT

Intro

The GeForce GTX 1080 features a clock speed of 1607 MHz and a GDDR5X memory frequency of 1251 MHz. It also features a 256-bit memory bus, and makes use of a 16 nm design. It is made up of 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

Compare all of that to the Radeon RX 5600 XT, which makes use of a 7 nm design. AMD has clocked the core frequency at 1375 MHz. The GDDR6 RAM works at a frequency of 1500 MHz on this particular model. It features 2304 SPUs as well as 144 TAUs and 64 Rasterization Operator Units.

GeForce GTX 1080 327680 MB/sec
Difference: 16384 (5%)

Texel Rate

The GeForce GTX 1080 should be quite a bit (more or less 30%) more effective at 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

The GeForce GTX 1080 will be just a bit (approximately 17%) faster with regards to anti-aliasing than the Radeon RX 5600 XT, and will be able to handle higher screen resolutions without slowing down too much. (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.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved across 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, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

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