GeForce 810M vs GeForce GTX 570

Intro

Compare that to the GeForce GTX 570, which features a core clock frequency of 732 MHz and a GDDR5 memory speed of 950 MHz. It also features a 320-bit bus, and uses a 40 nm design. It is comprised of 480 SPUs, 60 Texture Address Units, and 40 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
GeForce GTX 570		219 Watts
	Difference: 204 Watts (1360%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 570 will be 956% faster than the GeForce 810M overall, due to its greater bandwidth. (explain)

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

Texel Rate

The GeForce GTX 570 is quite a bit (more or less 644%) better at AF than the GeForce 810M. (explain)

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

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 570 is the winner, and very much so. (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 information (measured in megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
