Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M380 is 50% quicker than the GeForce GTX 960M in general, because of its greater bandwidth. (explain)

Radeon R9 M380		96000 MB/sec
GeForce GTX 960M		64000 MB/sec
	Difference: 32000 (50%)

Texel Rate

The GeForce GTX 960M should be a bit (approximately 10%) faster with regards to texture filtering than the Radeon R9 M380. (explain)

GeForce GTX 960M		43840 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 3840 (10%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 960M is a better choice, not by a very large margin though. (explain)

GeForce GTX 960M		17536 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 1536 (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 max amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one 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 worked out by multiplying the number of Raster Operations Pipelines 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
