Radeon R9 M375X vs Radeon RX 460

Intro

Compare those specifications to the Radeon RX 460, which comes with a clock frequency of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 128-bit memory bus, and makes use of a 14 nm design. It is comprised of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon RX 460 should be quite a bit faster than the Radeon R9 M375X in general. (explain)

Radeon RX 460		112000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 40000 (56%)

Texel Rate

The Radeon RX 460 should be a lot (more or less 50%) faster with regards to AF than the Radeon R9 M375X. (explain)

Radeon RX 460		61040 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 20440 (50%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 460 is the winner, though not by far. (explain)

Radeon RX 460		17440 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 1200 (7%)

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 information (counted in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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