Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
GeForce GTX 780 Ti		250 Watts
	Difference: 235 Watts (1567%)

Memory Bandwidth

In theory, the GeForce GTX 780 Ti will be 2233% faster than the GeForce 810M in general, because of its higher data rate. (explain)

GeForce GTX 780 Ti		336000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 321600 (2233%)

Texel Rate

The GeForce GTX 780 Ti will be quite a bit (more or less 3457%) better at anisotropic filtering than the GeForce 810M. (explain)

GeForce GTX 780 Ti		210000 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 204096 (3457%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 780 Ti is the winner, and very much so. (explain)

GeForce GTX 780 Ti		42000 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 39048 (1323%)

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 (in units of megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling 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 the video card 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 amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
