Radeon R7 M260X vs Radeon R9 Fury X

Intro

Compare all of that to the Radeon R9 Fury X, which features core speeds of 1050 MHz on the GPU, and 500 MHz on the 4096 MB of HBM memory. It features 4096 SPUs as well as 256 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 Fury X is 700% faster than the Radeon R7 M260X in general, because of its greater bandwidth. (explain)

Radeon R9 Fury X		512000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 448000 (700%)

Texel Rate

The Radeon R9 Fury X is quite a bit (about 1258%) better at AF than the Radeon R7 M260X. (explain)

Radeon R9 Fury X		268800 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 249000 (1258%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 Fury X is the winner, by a large margin. (explain)

Radeon R9 Fury X		67200 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 60600 (918%)

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 max amount of data (counted in megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units 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 rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
