GeForce 810M vs GeForce GTX 580

Intro

Compare all of that to the GeForce GTX 580, which makes use of a 40 nm design. nVidia has clocked the core frequency at 772 MHz. The GDDR5 RAM runs at a frequency of 1002 MHz on this model. It features 512 SPUs as well as 64 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
GeForce GTX 580		244 Watts
	Difference: 229 Watts (1527%)

Memory Bandwidth

Performance-wise, the GeForce GTX 580 should theoretically be quite a bit superior to the GeForce 810M overall. (explain)

GeForce GTX 580		192384 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 177984 (1236%)

Texel Rate

The GeForce GTX 580 is a lot (about 737%) better at texture filtering than the GeForce 810M. (explain)

GeForce GTX 580		49408 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 43504 (737%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 580 is the winner, by far. (explain)

GeForce GTX 580		37056 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 34104 (1155%)

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 information (counted in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at 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 that the graphics card can possibly record to the local memory per 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 - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
