GeForce RTX 2080 SUPER vs Radeon RX 5600

Intro

Compare those specifications to the Radeon RX 5600, which has GPU clock speed of 1375 MHz, and 6144 MB of GDDR6 memory running at 1500 MHz through a 192-bit bus. It also features 2048 SPUs, 128 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600		150 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 100 Watts (67%)

Memory Bandwidth

In theory, the GeForce RTX 2080 SUPER should be 72% faster than the Radeon RX 5600 overall, because of its greater bandwidth. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Radeon RX 5600		294912 MB/sec
	Difference: 212992 (72%)

Texel Rate

The GeForce RTX 2080 SUPER will be quite a bit (more or less 80%) faster with regards to texture filtering than the Radeon RX 5600. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon RX 5600		176000 Mtexels/sec
	Difference: 140800 (80%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 2080 SUPER is a better choice, but not by far. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon RX 5600		88000 Mpixels/sec
	Difference: 17600 (20%)

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: Bandwidth is the largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 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 higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
