Radeon RX 550 vs Radeon RX 6900 XT

Intro

Compare those specifications to the Radeon RX 6900 XT, which comes with a core clock speed of 1825 MHz and a GDDR6 memory speed of 2000 MHz. It also makes use of a 256-bit bus, and makes use of a 7 nm design. It is made up of 5120 SPUs, 320 Texture Address Units, and 128 ROPs.

Radeon RX 550		50 Watts
Radeon RX 6900 XT		300 Watts
	Difference: 250 Watts (500%)

Memory Bandwidth

The Radeon RX 6900 XT should in theory perform a lot faster than the Radeon RX 550 in general. (explain)

Radeon RX 6900 XT		524288 MB/sec
Radeon RX 550		114688 MB/sec
	Difference: 409600 (357%)

Texel Rate

The Radeon RX 6900 XT is quite a bit (about 1559%) faster with regards to AF than the Radeon RX 550. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 548800 (1559%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6900 XT is a better choice, and very much so. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 216000 (1227%)

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 data (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 are applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling 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 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 amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
