Radeon R9 Fury X vs Radeon R9 M375X

Intro

Compare those specifications to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has set the core speed at 1015 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this specific model. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 Fury X should theoretically be quite a bit better than the Radeon R9 M375X overall. (explain)

Radeon R9 Fury X		512000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 440000 (611%)

Texel Rate

The Radeon R9 Fury X is a lot (about 562%) faster with regards to AF than the Radeon R9 M375X. (explain)

Radeon R9 Fury X		268800 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 228200 (562%)

Pixel Rate

The Radeon R9 Fury X is quite a bit (more or less 314%) more effective at AA than the Radeon R9 M375X, and should be capable of handling higher resolutions without slowing down too much. (explain)

Radeon R9 Fury X		67200 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 50960 (314%)

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 maximum amount of information (measured in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics 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 most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
