GeForce RTX 2080 SUPER vs Radeon RX 5700

Intro

Compare those specifications to the Radeon RX 5700, which has GPU clock speed of 1465 MHz, and 8096 MB of GDDR6 memory set to run at 1750 MHz through a 256-bit bus. It also is made up of 2304 Stream Processors, 144 Texture Address Units, and 64 ROPs.

Radeon RX 5700		458752 MB/sec
	Difference: 49152 (11%)

Texel Rate

The GeForce RTX 2080 SUPER will be quite a bit (about 50%) more effective at anisotropic filtering than the Radeon RX 5700. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 105840 (50%)

Pixel Rate

The GeForce RTX 2080 SUPER is a little bit (more or less 13%) better at full screen anti-aliasing than the Radeon RX 5700, and should be capable of handling higher resolutions better. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon RX 5700		93760 Mpixels/sec
	Difference: 11840 (13%)

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 megabytes per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video 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 that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
