Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the Geforce GTX 780 is 1903% quicker than the GeForce 810M in general, due to its greater bandwidth. (explain)

Geforce GTX 780		288384 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 273984 (1903%)

Texel Rate

The Geforce GTX 780 should be quite a bit (approximately 2707%) better at anisotropic filtering than the GeForce 810M. (explain)

Geforce GTX 780		165696 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 159792 (2707%)

Pixel Rate

If using a high screen resolution is important to you, then the Geforce GTX 780 is the winner, and very much so. (explain)

Geforce GTX 780		41424 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 38472 (1303%)

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 largest amount of data (counted in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number 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 outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
