Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon R9 Fury X should in theory be quite a bit faster than the Radeon R9 390X 8G in general. (explain)

Radeon R9 Fury X		512000 MB/sec
Radeon R9 390X 8G		384000 MB/sec
	Difference: 128000 (33%)

Texel Rate

The Radeon R9 Fury X will be quite a bit (more or less 45%) faster with regards to AF than the Radeon R9 390X 8G. (explain)

Radeon R9 Fury X		268800 Mtexels/sec
Radeon R9 390X 8G		184800 Mtexels/sec
	Difference: 84000 (45%)

Pixel Rate

Both cards have exactly the same pixel fill rate, so theoretically they should perform equally good at at FSAA, and be capable of handling the same resolutions. (explain)

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 largest amount of data (counted in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
