Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375 is 10% quicker than the GeForce GTX 850M overall, due to its higher data rate. (explain)

Radeon R9 M375		35200 MB/sec
GeForce GTX 850M		32000 MB/sec
	Difference: 3200 (10%)

Texel Rate

The Radeon R9 M375 is just a bit (about 16%) faster with regards to anisotropic filtering than the GeForce GTX 850M. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GTX 850M		35040 Mtexels/sec
	Difference: 5560 (16%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M375 is superior to the GeForce GTX 850M, though only just barely. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce GTX 850M		14016 Mpixels/sec
	Difference: 2224 (16%)

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 (counted in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units by the core 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
