Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 1060 should be 105% quicker than the Radeon R9 M385X in general, due to its greater data rate. (explain)

GeForce GTX 1060		196608 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 100608 (105%)

Texel Rate

The GeForce GTX 1060 will be a lot (more or less 96%) faster with regards to anisotropic filtering than the Radeon R9 M385X. (explain)

GeForce GTX 1060		120480 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 58880 (96%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 1060 is a better choice, by a large margin. (explain)

GeForce GTX 1060		72288 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 54688 (311%)

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 (in units of megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must 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 high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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