Radeon RX 550 vs Radeon RX 5700 XT

Intro

Compare those specifications to the Radeon RX 5700 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 1605 MHz. The GDDR6 memory is set to run at a speed of 1750 MHz on this particular model. It features 2560 SPUs as well as 160 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
Radeon RX 5700 XT		225 Watts
	Difference: 175 Watts (350%)

Memory Bandwidth

In theory, the Radeon RX 5700 XT should perform a lot faster than the Radeon RX 550 overall. (explain)

Radeon RX 5700 XT		458752 MB/sec
Radeon RX 550		114688 MB/sec
	Difference: 344064 (300%)

Texel Rate

The Radeon RX 5700 XT will be much (more or less 630%) more effective 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 running with lots of anti-aliasing is important to you, then the Radeon RX 5700 XT is a better choice, 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 (in units of MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
