Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375 should be 10% quicker than the GeForce GTX 950M in general, due to its greater bandwidth. (explain)

Radeon R9 M375		35200 MB/sec
GeForce GTX 950M		32000 MB/sec
	Difference: 3200 (10%)

Texel Rate

The Radeon R9 M375 should be a little bit (approximately 11%) more effective at texture filtering than the GeForce GTX 950M. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GTX 950M		36560 Mtexels/sec
	Difference: 4040 (11%)

Pixel Rate

The Radeon R9 M375 should be a bit (approximately 11%) better at AA than the GeForce GTX 950M, and also will be capable of handling higher resolutions while still performing well. (explain)

Radeon R9 M375		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 information (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed 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 this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
