Memory Bandwidth

Theoretically speaking, the Radeon RX 550 will be 2% faster than the Radeon RX 460 overall, because of its greater bandwidth. (explain)

Radeon RX 550		114688 MB/sec
Radeon RX 460		112000 MB/sec
	Difference: 2688 (2%)

Texel Rate

The Radeon RX 460 should be quite a bit (about 73%) better at texture filtering than the Radeon RX 550. (explain)

Radeon RX 460		61040 Mtexels/sec
Radeon RX 550		35200 Mtexels/sec
	Difference: 25840 (73%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 550 is the winner, though only just barely. (explain)

Radeon RX 550		17600 Mpixels/sec
Radeon RX 460		17440 Mpixels/sec
	Difference: 160 (1%)

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 MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
