Radeon R9 Fury X vs Radeon R9 M270X

Intro

Compare all of that to the Radeon R9 M270X, which features core clock speeds of 725 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 Fury X should be 611% faster than the Radeon R9 M270X in general, due to its greater bandwidth. (explain)

Radeon R9 Fury X		512000 MB/sec
Radeon R9 M270X		72000 MB/sec
	Difference: 440000 (611%)

Texel Rate

The Radeon R9 Fury X is much (approximately 827%) more effective at anisotropic filtering than the Radeon R9 M270X. (explain)

Radeon R9 Fury X		268800 Mtexels/sec
Radeon R9 M270X		29000 Mtexels/sec
	Difference: 239800 (827%)

Pixel Rate

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

Radeon R9 Fury X		67200 Mpixels/sec
Radeon R9 M270X		11600 Mpixels/sec
	Difference: 55600 (479%)

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 MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, the result 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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