Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
GeForce GTX 590		365 Watts
	Difference: 350 Watts (2333%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 590 will be 2180% faster than the GeForce 810M overall, because of its higher bandwidth. (explain)

GeForce GTX 590		328320 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 313920 (2180%)

Texel Rate

The GeForce GTX 590 will be much (more or less 1216%) better at AF than the GeForce 810M. (explain)

GeForce GTX 590		77696 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 71792 (1216%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 590 is the winner, and very much so. (explain)

GeForce GTX 590		58272 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 55320 (1874%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 applied per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
