Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 950 will be 10% quicker than the Radeon R9 M380 overall, because of its greater bandwidth. (explain)

GeForce GTX 950		105728 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 9728 (10%)

Texel Rate

The GeForce GTX 950 should be quite a bit (approximately 23%) more effective at AF than the Radeon R9 M380. (explain)

GeForce GTX 950		49152 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 9152 (23%)

Pixel Rate

The GeForce GTX 950 should be much (about 105%) more effective at FSAA than the Radeon R9 M380, and also will be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 950		32768 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 16768 (105%)

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 max amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed 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 card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
