Radeon R9 M375 vs Radeon RX 470

Intro

Compare all of that to the Radeon RX 470, which comes with core speeds of 926 MHz on the GPU, and 1650 MHz on the 8192 MB of GDDR5 memory. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

Radeon R9 M375		40600 Mtexels/sec
	Difference: 77928 (192%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 470 is the winner, by far. (explain)

Radeon RX 470		29632 Mpixels/sec
Radeon R9 M375		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 megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
