Radeon RX 470 4GB		120 Watts
Radeon RX 5500		150 Watts
	Difference: 30 Watts (25%)

Memory Bandwidth

In theory, the Radeon RX 5500 will be 9% faster than the Radeon RX 470 4GB in general, because of its greater bandwidth. (explain)

Radeon RX 5500		229376 MB/sec
Radeon RX 470 4GB		211200 MB/sec
	Difference: 18176 (9%)

Texel Rate

The Radeon RX 5500 will be quite a bit (more or less 24%) faster with regards to anisotropic filtering than the Radeon RX 470 4GB. (explain)

Radeon RX 5500		146960 Mtexels/sec
Radeon RX 470 4GB		118528 Mtexels/sec
	Difference: 28432 (24%)

Pixel Rate

The Radeon RX 5500 should be a lot (approximately 80%) faster with regards to full screen anti-aliasing than the Radeon RX 470 4GB, and able to handle higher resolutions more effectively. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon RX 470 4GB		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 MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock 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 output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
