Radeon RX 550 vs Radeon RX 5700 XT

Intro

Compare that to the Radeon RX 5700 XT, which uses a 7 nm design. AMD has clocked the core frequency at 1605 MHz. The GDDR6 RAM works at a speed of 1750 MHz on this specific model. It features 2560 SPUs along with 160 Texture Address Units and 64 Rasterization Operator Units.

Radeon RX 550		114688 MB/sec
	Difference: 344064 (300%)

Texel Rate

The Radeon RX 5700 XT will be quite a bit (approximately 630%) better at anisotropic filtering than the Radeon RX 550. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 221600 (630%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 5700 XT is superior to the Radeon RX 550, and very much so. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 85120 (484%)

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 max amount of information (counted in MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
