Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
Radeon R9 380X		190 Watts
	Difference: 175 Watts (1167%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 380X should be 1167% quicker than the GeForce 810M in general, because of its greater data rate. (explain)

Radeon R9 380X		182400 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 168000 (1167%)

Texel Rate

The Radeon R9 380X will be a lot (about 2003%) more effective at anisotropic filtering than the GeForce 810M. (explain)

Radeon R9 380X		124160 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 118256 (2003%)

Pixel Rate

The Radeon R9 380X is quite a bit (approximately 951%) more effective at FSAA than the GeForce 810M, and also will be able to handle higher resolutions without losing too much performance. (explain)

Radeon R9 380X		31040 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 28088 (951%)

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 information (measured in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
