Radeon R9 M375X vs Radeon RX 470

Intro

Compare those specifications to the Radeon RX 470, which comes with a clock speed of 926 MHz and a GDDR5 memory frequency of 1650 MHz. It also makes use of a 256-bit bus, and makes use of a 14 nm design. It features 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 470, in theory, should be quite a bit faster than the Radeon R9 M375X in general. (explain)

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

Texel Rate

The Radeon RX 470 will be much (approximately 192%) better at AF than the Radeon R9 M375X. (explain)

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

Pixel Rate

The Radeon RX 470 should be a lot (more or less 82%) better at full screen anti-aliasing than the Radeon R9 M375X, and will be capable of handling higher resolutions more effectively. (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 max amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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