Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 Fury X should perform quite a bit faster than the Radeon R9 M385X in general. (explain)

Radeon R9 Fury X		512000 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 416000 (433%)

Texel Rate

The Radeon R9 Fury X is quite a bit (about 336%) more effective at texture filtering than the Radeon R9 M385X. (explain)

Radeon R9 Fury X		268800 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 207200 (336%)

Pixel Rate

The Radeon R9 Fury X will be quite a bit (about 282%) better at AA than the Radeon R9 M385X, and also should be able to handle higher resolutions without slowing down too much. (explain)

Radeon R9 Fury X		67200 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 49600 (282%)

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 information (measured in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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 quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
