Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 480 4GB		150 Watts
Radeon RX 5700 XT		225 Watts
	Difference: 75 Watts (50%)

Memory Bandwidth

In theory, the Radeon RX 5700 XT should perform much faster than the Radeon RX 480 4GB in general. (explain)

Radeon RX 5700 XT		458752 MB/sec
Radeon RX 480 4GB		229376 MB/sec
	Difference: 229376 (100%)

Texel Rate

The Radeon RX 5700 XT is quite a bit (more or less 59%) faster with regards to anisotropic filtering than the Radeon RX 480 4GB. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
Radeon RX 480 4GB		161280 Mtexels/sec
	Difference: 95520 (59%)

Pixel Rate

The Radeon RX 5700 XT should be a lot (more or less 187%) more effective at full screen anti-aliasing than the Radeon RX 480 4GB, and also capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Radeon RX 480 4GB		35840 Mpixels/sec
	Difference: 66880 (187%)

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 largest amount of information (measured in MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling 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 video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
