GeForce RTX 2080 SUPER vs Radeon RX 5700 XT

Intro

Compare all of that to the Radeon RX 5700 XT, which features core clock speeds of 1605 MHz on the GPU, and 1750 MHz on the 8096 MB of GDDR6 RAM. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700 XT		225 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 25 Watts (11%)

Memory Bandwidth

Performance-wise, the GeForce RTX 2080 SUPER should in theory be a bit superior to the Radeon RX 5700 XT overall. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Radeon RX 5700 XT		458752 MB/sec
	Difference: 49152 (11%)

Texel Rate

The GeForce RTX 2080 SUPER is much (more or less 23%) better at texture filtering than the Radeon RX 5700 XT. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon RX 5700 XT		256800 Mtexels/sec
	Difference: 60000 (23%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 2080 SUPER is a better choice, but it probably won't make a huge difference. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon RX 5700 XT		102720 Mpixels/sec
	Difference: 2880 (3%)

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 maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the 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 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 output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
