GeForce GTX 460 1GB		160 Watts
	Difference: 145 Watts (967%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 1GB should be 700% quicker than the GeForce 810M in general, because of its greater data rate. (explain)

GeForce GTX 460 1GB		115200 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 100800 (700%)

Texel Rate

The GeForce GTX 460 1GB should be much (about 540%) faster with regards to texture filtering than the GeForce 810M. (explain)

GeForce GTX 460 1GB		37800 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 31896 (540%)

Pixel Rate

The GeForce GTX 460 1GB should be a lot (approximately 632%) more effective at full screen anti-aliasing than the GeForce 810M, and capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 18648 (632%)

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 information (measured in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 are processed per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's 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 lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
