GeForce RTX 2080 SUPER vs Radeon RX 480

Intro

Compare those specs to the Radeon RX 480, which uses a 14 nm design. AMD has set the core frequency at 1120 MHz. The GDDR5 memory runs at a frequency of 2000 MHz on this particular model. It features 2304 SPUs along with 144 TAUs and 32 Rasterization Operator Units.

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

Texel Rate

The GeForce RTX 2080 SUPER is much (about 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 superior to the Radeon RX 480, 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 data (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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