In theory, the GeForce GTX 1060 should be 23% quicker than the Radeon R9 M395X overall, due to its higher data rate. (explain)

GeForce GTX 1060		196608 MB/sec
Radeon R9 M395X		160000 MB/sec
	Difference: 36608 (23%)

Texel Rate

The GeForce GTX 1060 is much (more or less 30%) more effective at anisotropic filtering than the Radeon R9 M395X. (explain)

GeForce GTX 1060		120480 Mtexels/sec
Radeon R9 M395X		92544 Mtexels/sec
	Difference: 27936 (30%)

Pixel Rate

The GeForce GTX 1060 should be quite a bit (approximately 212%) better at full screen anti-aliasing than the Radeon R9 M395X, and also able to handle higher resolutions more effectively. (explain)

GeForce GTX 1060		72288 Mpixels/sec
Radeon R9 M395X		23136 Mpixels/sec
	Difference: 49152 (212%)

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 information (measured in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics 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 maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
