Radeon RX 550 vs Radeon RX 5600 XT

Intro

Compare those specifications to the Radeon RX 5600 XT, which has clock speeds of 1375 MHz on the GPU, and 1500 MHz on the 6144 MB of GDDR6 RAM. It features 2304 SPUs along with 144 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 550		50 Watts
Radeon RX 5600 XT		160 Watts
	Difference: 110 Watts (220%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5600 XT will be 200% faster than the Radeon RX 550 overall, because of its greater data rate. (explain)

Radeon RX 5600 XT		344064 MB/sec
Radeon RX 550		114688 MB/sec
	Difference: 229376 (200%)

Texel Rate

The Radeon RX 5600 XT is much (more or less 463%) more effective at texture filtering than the Radeon RX 550. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 162800 (463%)

Pixel Rate

The Radeon RX 5600 XT is a lot (about 400%) more effective at anti-aliasing than the Radeon RX 550, and also will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 70400 (400%)

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 largest amount of data (measured in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card 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 most pixels that the graphics card can possibly record to the 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 core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
