GeForce 810M		15 Watts
Radeon R9 390 8G		275 Watts
	Difference: 260 Watts (1733%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 390 8G should be 2567% quicker than the GeForce 810M in general, because of its greater bandwidth. (explain)

Radeon R9 390 8G		384000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 369600 (2567%)

Texel Rate

The Radeon R9 390 8G should be quite a bit (approximately 2610%) better at anisotropic filtering than the GeForce 810M. (explain)

Radeon R9 390 8G		160000 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 154096 (2610%)

Pixel Rate

The Radeon R9 390 8G should be a lot (about 2068%) faster with regards to anti-aliasing than the GeForce 810M, and also able to handle higher resolutions without slowing down too much. (explain)

Radeon R9 390 8G		64000 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 61048 (2068%)

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 (in units of megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, 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 number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units 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 output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
