Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M365X is 105% quicker than the Radeon R9 M375 in general, because of its greater data rate. (explain)

Radeon R9 M365X		72000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 36800 (105%)

Texel Rate

The Radeon R9 M375 should be just a bit (about 10%) faster with regards to AF than the Radeon R9 M365X. (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 3600 (10%)

Pixel Rate

The Radeon R9 M375 should be just a bit (approximately 10%) more effective at AA than the Radeon R9 M365X, and should be able to handle higher resolutions without slowing down too much. (explain)

Radeon R9 M375		16240 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 1440 (10%)

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 moved across the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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