Radeon RX 550 vs Radeon RX 5600 XT

Intro

Compare those specifications to the Radeon RX 5600 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 1375 MHz. The GDDR6 RAM is set to run at a frequency of 1500 MHz on this particular card. It features 2304 SPUs along with 144 TAUs 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

In theory, the Radeon RX 5600 XT is 200% quicker than the Radeon RX 550 in general, 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 quite a bit (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

If running with high levels of AA is important to you, then the Radeon RX 5600 XT is superior to the Radeon RX 550, by a large margin. (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 information (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
