Radeon RX 480 vs Radeon RX 5700 XT

Intro

Compare those specifications to the Radeon RX 5700 XT, which has clock speeds of 1605 MHz on the GPU, and 1750 MHz on the 8096 MB of GDDR6 memory. It features 2560 SPUs as well as 160 Texture Address Units and 64 Rasterization Operator Units.

Memory Bandwidth

In theory, the Radeon RX 5700 XT should perform quite a bit faster than the Radeon RX 480 overall. (explain)

Radeon RX 5700 XT		458752 MB/sec
Radeon RX 480		262144 MB/sec
	Difference: 196608 (75%)

Texel Rate

The Radeon RX 5700 XT will be much (more or less 59%) better at texture filtering than the Radeon RX 480. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
Radeon RX 480		161280 Mtexels/sec
	Difference: 95520 (59%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 5700 XT is the winner, by a large margin. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Radeon RX 480		35840 Mpixels/sec
	Difference: 66880 (187%)

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 max amount of information (counted in megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
