Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 370 4G, in theory, should perform quite a bit faster than the Radeon R9 M375X overall. (explain)

Radeon R7 370 4G		179200 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 107200 (149%)

Texel Rate

The Radeon R7 370 4G will be quite a bit (approximately 54%) better at anisotropic filtering than the Radeon R9 M375X. (explain)

Radeon R7 370 4G		62400 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 21800 (54%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R7 370 4G is a better choice, by a large margin. (explain)

Radeon R7 370 4G		31200 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 14960 (92%)

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 largest amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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.
