Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 5500 XT should in theory perform much faster than the Radeon R9 M380 in general. (explain)

Radeon RX 5500 XT		229376 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 133376 (139%)

Texel Rate

The Radeon RX 5500 XT is a lot (more or less 278%) better at texture filtering than the Radeon R9 M380. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 111096 (278%)

Pixel Rate

The Radeon RX 5500 XT should be quite a bit (about 243%) faster with regards to AA than the Radeon R9 M380, and also should be able to handle higher screen resolutions more effectively. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 38944 (243%)

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 information (counted in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
