Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M380 should be quite a bit faster than the GeForce GTX 950M in general. (explain)

Radeon R9 M380		96000 MB/sec
GeForce GTX 950M		32000 MB/sec
	Difference: 64000 (200%)

Texel Rate

The Radeon R9 M380 will be just a bit (approximately 9%) more effective at AF than the GeForce GTX 950M. (explain)

Radeon R9 M380		40000 Mtexels/sec
GeForce GTX 950M		36560 Mtexels/sec
	Difference: 3440 (9%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M380 is the winner, but only just. (explain)

Radeon R9 M380		16000 Mpixels/sec
GeForce GTX 950M		14624 Mpixels/sec
	Difference: 1376 (9%)

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 (measured in megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
