GeForce RTX 3080 vs Radeon RX 5600 XT

Intro

Compare those specifications to the Radeon RX 5600 XT, which features a core clock frequency of 1375 MHz and a GDDR6 memory frequency of 1500 MHz. It also makes use of a 192-bit memory bus, and makes use of a 7 nm design. It features 2304 SPUs, 144 TAUs, and 64 Raster Operation Units.

Radeon RX 5600 XT		344064 MB/sec
	Difference: 434483 (126%)

Texel Rate

The GeForce RTX 3080 should be quite a bit (about 98%) better at anisotropic filtering than the Radeon RX 5600 XT. (explain)

GeForce RTX 3080		391680 Mtexels/sec
Radeon RX 5600 XT		198000 Mtexels/sec
	Difference: 193680 (98%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 3080 is superior to the Radeon RX 5600 XT, and very much so. (explain)

GeForce RTX 3080		138240 Mpixels/sec
Radeon RX 5600 XT		88000 Mpixels/sec
	Difference: 50240 (57%)

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 information (in units of megabytes per second) that can be moved past the external memory interface in a second. The number is calculated 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
