Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 6800 XT is 446% quicker than the Radeon R9 M380 overall, because of its higher bandwidth. (explain)

Radeon RX 6800 XT		524288 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 428288 (446%)

Texel Rate

The Radeon RX 6800 XT should be much (more or less 1214%) better at AF than the Radeon R9 M380. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 485600 (1214%)

Pixel Rate

The Radeon RX 6800 XT is much (more or less 1360%) better at full screen anti-aliasing than the Radeon R9 M380, and also will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 217600 (1360%)

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 max amount of data (counted in MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 texture map elements (texels) that are applied 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the 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 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
