Radeon RX 550		114688 MB/sec
	Difference: 96512 (84%)

Texel Rate

The Radeon RX 470 should be quite a bit (more or less 237%) faster with regards to anisotropic filtering than the Radeon RX 550. (explain)

Radeon RX 470		118528 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 83328 (237%)

Pixel Rate

The Radeon RX 470 will be a lot (about 68%) better at full screen anti-aliasing than the Radeon RX 550, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 470		29632 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 12032 (68%)

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 information (counted in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. 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 is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
