Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 950 should be 47% quicker than the Radeon R9 M375X in general, because of its higher bandwidth. (explain)

GeForce GTX 950		105728 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 33728 (47%)

Texel Rate

The GeForce GTX 950 will be quite a bit (approximately 21%) more effective at texture filtering than the Radeon R9 M375X. (explain)

GeForce GTX 950		49152 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 8552 (21%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 950 is superior to the Radeon R9 M375X, by far. (explain)

GeForce GTX 950		32768 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 16528 (102%)

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 data (in units of megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 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 speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one 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 - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of 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.
