	Difference: 204 Watts (1360%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 570 is 956% faster than the GeForce 810M in general, due to its higher data rate. (explain)

GeForce GTX 570		152000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 137600 (956%)

Texel Rate

The GeForce GTX 570 is a lot (approximately 644%) faster with regards to texture filtering than the GeForce 810M. (explain)

GeForce GTX 570		43920 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 38016 (644%)

Pixel Rate

The GeForce GTX 570 should be quite a bit (more or less 892%) faster with regards to full screen anti-aliasing than the GeForce 810M, and also able to handle higher resolutions better. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 26328 (892%)

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 transferred across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
