GeForce RTX 2080 SUPER vs Radeon RX 480

Intro

Compare all of that to the Radeon RX 480, which comes with a clock speed of 1120 MHz and a GDDR5 memory speed of 2000 MHz. It also uses a 256-bit memory bus, and uses a 14 nm design. It is made up of 2304 SPUs, 144 Texture Address Units, and 32 Raster Operation Units.

Radeon RX 480		262144 MB/sec
	Difference: 245760 (94%)

Texel Rate

The GeForce RTX 2080 SUPER will be much (approximately 96%) faster with regards to AF than the Radeon RX 480. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon RX 480		161280 Mtexels/sec
	Difference: 155520 (96%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 2080 SUPER is the winner, and very much so. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon RX 480		35840 Mpixels/sec
	Difference: 69760 (195%)

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 maximum amount of information (measured in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses 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 processed per second. This is worked out 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
