Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 5700 XT 50th Anniversary Edition should in theory perform much faster than the Radeon R9 M380 in general. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		458752 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 362752 (378%)

Texel Rate

The Radeon RX 5700 XT 50th Anniversary Edition should be a lot (approximately 572%) better at anisotropic filtering than the Radeon R9 M380. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 228800 (572%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 5700 XT 50th Anniversary Edition is superior to the Radeon R9 M380, by far. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 91520 (572%)

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 data (in units of MB per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
