Radeon RX 480		150 Watts
Radeon RX 580		185 Watts
	Difference: 35 Watts (23%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so in theory they should have the same performance. (explain)

Texel Rate

The Radeon RX 580 will be a little bit (more or less 12%) faster with regards to AF than the Radeon RX 480. (explain)

Radeon RX 580		181008 Mtexels/sec
Radeon RX 480		161280 Mtexels/sec
	Difference: 19728 (12%)

Pixel Rate

The Radeon RX 580 should be a small bit (about 12%) faster with regards to full screen anti-aliasing than the Radeon RX 480, and should be able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 580		40224 Mpixels/sec
Radeon RX 480		35840 Mpixels/sec
	Difference: 4384 (12%)

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 maximum amount of information (counted in MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 can be processed per second. This number is calculated by multiplying the total texture units of the card by the core clock 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
