Radeon R9 M390X		160000 MB/sec
	Difference: 36608 (23%)

Texel Rate

The GeForce GTX 1060 3GB will be a little bit (approximately 17%) more effective at anisotropic filtering than the Radeon R9 M390X. (explain)

GeForce GTX 1060 3GB		108432 Mtexels/sec
Radeon R9 M390X		92544 Mtexels/sec
	Difference: 15888 (17%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 1060 3GB is the winner, and very much so. (explain)

GeForce GTX 1060 3GB		72288 Mpixels/sec
Radeon R9 M390X		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 data (measured in MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
