Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon RX 5700 XT 50th Anniversary Edition should in theory be much superior to the Radeon R9 M385X in general. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		458752 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 362752 (378%)

Texel Rate

The Radeon RX 5700 XT 50th Anniversary Edition should be much (more or less 336%) more effective at AF than the Radeon R9 M385X. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 207200 (336%)

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 M385X, by a large margin. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 89920 (511%)

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 maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling 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 can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number 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 filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
