Radeon R9 M375X vs Radeon RX 470 4GB

Intro

Compare all that to the Radeon RX 470 4GB, which features a core clock speed of 926 MHz and a GDDR5 memory frequency of 1650 MHz. It also uses a 256-bit memory bus, and makes use of a 14 nm design. It is made up of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Radeon R9 M375X		40600 Mtexels/sec
	Difference: 77928 (192%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 470 4GB is a better choice, by a large margin. (explain)

Radeon RX 470 4GB		29632 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 13392 (82%)

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 maximum amount of data (counted in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied 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 better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
