GeForce 810M		15 Watts
Radeon R9 270		150 Watts
	Difference: 135 Watts (900%)

Memory Bandwidth

In theory, the Radeon R9 270 should be 1144% faster than the GeForce 810M in general, because of its higher data rate. (explain)

Radeon R9 270		179200 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 164800 (1144%)

Texel Rate

The Radeon R9 270 is much (more or less 1120%) better at AF than the GeForce 810M. (explain)

Radeon R9 270		72000 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 66096 (1120%)

Pixel Rate

The Radeon R9 270 is much (approximately 876%) better at anti-aliasing than the GeForce 810M, and will be capable of handling higher resolutions better. (explain)

Radeon R9 270		28800 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 25848 (876%)

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 maximum amount of data (measured in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per 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 better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
