Radeon RX 480 4GB		229376 MB/sec
	Difference: 32768 (14%)

Texel Rate

The Radeon RX 580 should be a little bit (more or less 12%) more effective at texture filtering than the Radeon RX 480 4GB. (explain)

Radeon RX 580		181008 Mtexels/sec
Radeon RX 480 4GB		161280 Mtexels/sec
	Difference: 19728 (12%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 580 is a better choice, but it probably won't make a huge difference. (explain)

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
