GeForce 810M vs GeForce GTX 470

Intro

Compare those specifications to the GeForce GTX 470, which uses a 40 nm design. nVidia has set the core frequency at 607 MHz. The GDDR5 memory is set to run at a speed of 837 MHz on this particular model. It features 448 SPUs along with 56 TAUs and 40 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
GeForce GTX 470		215 Watts
	Difference: 200 Watts (1333%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 470 should theoretically be quite a bit superior to the GeForce 810M in general. (explain)

GeForce GTX 470		133920 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 119520 (830%)

Texel Rate

The GeForce GTX 470 should be much (more or less 476%) better at texture filtering than the GeForce 810M. (explain)

GeForce GTX 470		33992 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 28088 (476%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 470 is superior to the GeForce 810M, and very much so. (explain)

GeForce GTX 470		24280 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 21328 (722%)

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 maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video 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 chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated 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 filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
