Radeon RX 550		114688 MB/sec
	Difference: 114688 (100%)

Texel Rate

The Radeon RX 570 should be quite a bit (more or less 325%) more effective at anisotropic filtering than the Radeon RX 550. (explain)

Radeon RX 570		149504 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 114304 (325%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 570 is superior to the Radeon RX 550, by far. (explain)

Radeon RX 570		37376 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 19776 (112%)

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 megabytes per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 most pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the card's 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
