Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the Radeon R7 370 4G is 87% quicker than the GeForce GTX 870M in general, because of its higher data rate. (explain)

Radeon R7 370 4G		179200 MB/sec
GeForce GTX 870M		96000 MB/sec
	Difference: 83200 (87%)

Texel Rate

The GeForce GTX 870M will be much (approximately 69%) better at anisotropic filtering than the Radeon R7 370 4G. (explain)

GeForce GTX 870M		105392 Mtexels/sec
Radeon R7 370 4G		62400 Mtexels/sec
	Difference: 42992 (69%)

Pixel Rate

The Radeon R7 370 4G will be quite a bit (about 38%) more effective at anti-aliasing than the GeForce GTX 870M, and able to handle higher screen resolutions better. (explain)

Radeon R7 370 4G		31200 Mpixels/sec
GeForce GTX 870M		22584 Mpixels/sec
	Difference: 8616 (38%)

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 largest amount of data (measured in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
