Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
GeForce GTX 980		165 Watts
	Difference: 150 Watts (1000%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 980 will be 1456% quicker than the GeForce 810M in general, because of its higher data rate. (explain)

GeForce GTX 980		224000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 209600 (1456%)

Texel Rate

The GeForce GTX 980 will be quite a bit (more or less 2341%) faster with regards to AF than the GeForce 810M. (explain)

GeForce GTX 980		144128 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 138224 (2341%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 980 is the winner, by a large margin. (explain)

GeForce GTX 980		72064 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 69112 (2341%)

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: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 processed in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
