Radeon R9 M375X vs Radeon RX 470

Intro

Compare those specs to the Radeon RX 470, which comes with a GPU core clock speed of 926 MHz, and 8192 MB of GDDR5 RAM running at 1650 MHz through a 256-bit bus. It also is made up of 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 470 should in theory perform quite a bit faster than the Radeon R9 M375X overall. (explain)

Radeon RX 470		211200 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 139200 (193%)

Texel Rate

The Radeon RX 470 is much (about 192%) more effective at anisotropic filtering than the Radeon R9 M375X. (explain)

Radeon RX 470		118528 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 77928 (192%)

Pixel Rate

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

Radeon RX 470		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: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
