Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon RX 5500 XT should perform much faster than the Radeon R9 M385X in general. (explain)

Radeon RX 5500 XT		229376 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 133376 (139%)

Texel Rate

The Radeon RX 5500 XT should be quite a bit (more or less 145%) faster with regards to texture filtering than the Radeon R9 M385X. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 89496 (145%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 5500 XT is a better choice, by a large margin. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 37344 (212%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units of the card 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 number of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
