Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 870M is 500% quicker than the Radeon R7 M360 overall, because of its higher bandwidth. (explain)

GeForce GTX 870M		96000 MB/sec
Radeon R7 M360		16000 MB/sec
	Difference: 80000 (500%)

Texel Rate

The GeForce GTX 870M is much (approximately 290%) more effective at texture filtering than the Radeon R7 M360. (explain)

GeForce GTX 870M		105392 Mtexels/sec
Radeon R7 M360		27000 Mtexels/sec
	Difference: 78392 (290%)

Pixel Rate

The GeForce GTX 870M is a lot (more or less 151%) more effective at anti-aliasing than the Radeon R7 M360, and capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 870M		22584 Mpixels/sec
Radeon R7 M360		9000 Mpixels/sec
	Difference: 13584 (151%)

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 largest amount of data (in units of MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 can be applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few 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.
