GeForce 810M		15 Watts
GeForce GTX 660 Ti		150 Watts
	Difference: 135 Watts (900%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 660 Ti is 900% faster than the GeForce 810M overall, due to its higher bandwidth. (explain)

GeForce GTX 660 Ti		144000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 129600 (900%)

Texel Rate

The GeForce GTX 660 Ti will be much (approximately 1636%) more effective at AF than the GeForce 810M. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 96576 (1636%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 660 Ti is a better choice, and very much so. (explain)

GeForce GTX 660 Ti		21960 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 19008 (644%)

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 data (counted in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant 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.
