The Radeon RX 590 is much (about 40%) more effective at AF than the Radeon RX 5500 XT. (explain)

Radeon RX 590		211536 Mtexels/sec
Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 60440 (40%)

Pixel Rate

The Radeon RX 5500 XT will be a bit (approximately 17%) more effective at anti-aliasing than the Radeon RX 590, and should be able to handle higher resolutions better. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 7936 (17%)

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 data (in units of megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the 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 maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
