Radeon RX 470		120 Watts
Radeon RX 5500		150 Watts
	Difference: 30 Watts (25%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5500 is 9% faster than the Radeon RX 470 in general, because of its greater bandwidth. (explain)

Radeon RX 5500		229376 MB/sec
Radeon RX 470		211200 MB/sec
	Difference: 18176 (9%)

Texel Rate

The Radeon RX 5500 will be much (approximately 24%) better at texture filtering than the Radeon RX 470. (explain)

Radeon RX 5500		146960 Mtexels/sec
Radeon RX 470		118528 Mtexels/sec
	Difference: 28432 (24%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 5500 is superior to the Radeon RX 470, by a large margin. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon RX 470		29632 Mpixels/sec
	Difference: 23808 (80%)

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 (in units of megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at 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 video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
