Power Consumption (Max TDP)

Radeon R9 M280X		75 Watts
Radeon R9 Fury X		275 Watts
	Difference: 200 Watts (267%)

Memory Bandwidth

In theory, the Radeon R9 Fury X is 482% faster than the Radeon R9 M280X in general, because of its greater bandwidth. (explain)

Radeon R9 Fury X		512000 MB/sec
Radeon R9 M280X		88000 MB/sec
	Difference: 424000 (482%)

Texel Rate

The Radeon R9 Fury X should be much (about 433%) better at texture filtering than the Radeon R9 M280X. (explain)

Radeon R9 Fury X		268800 Mtexels/sec
Radeon R9 M280X		50400 Mtexels/sec
	Difference: 218400 (433%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 Fury X is the winner, and very much so. (explain)

Radeon R9 Fury X		67200 Mpixels/sec
Radeon R9 M280X		14400 Mpixels/sec
	Difference: 52800 (367%)

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 megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If 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 per second. This figure is calculated by multiplying the total amount of texture units 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 amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
