Radeon R5 M230		16000 MB/sec
	Difference: 98688 (617%)

Texel Rate

The Radeon RX 550 should be a lot (more or less 126%) more effective at texture filtering than the Radeon R5 M230. (explain)

Radeon RX 550		35200 Mtexels/sec
Radeon R5 M230		15600 Mtexels/sec
	Difference: 19600 (126%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 550 is a better choice, by far. (explain)

Radeon RX 550		17600 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 14480 (464%)

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 (measured in megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
