Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375X will be 125% quicker than the GeForce GTX 950M overall, due to its higher bandwidth. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce GTX 950M		32000 MB/sec
	Difference: 40000 (125%)

Texel Rate

The Radeon R9 M375X is a bit (more or less 11%) faster with regards to texture filtering than the GeForce GTX 950M. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce GTX 950M		36560 Mtexels/sec
	Difference: 4040 (11%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M375X is the winner, but it probably won't make a huge difference. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce GTX 950M		14624 Mpixels/sec
	Difference: 1616 (11%)

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 (in units of MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of 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 speed of the chip. The higher this number, the better the 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 most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
