GeForce 810M vs GeForce 8600 GT 512MB GDDR3

Intro

Compare that to the GeForce 8600 GT 512MB GDDR3, which features a core clock speed of 540 MHz and a GDDR3 memory frequency of 700 MHz. It also features a 128-bit bus, and makes use of a 80 nm design. It is made up of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
GeForce 8600 GT 512MB GDDR3		47 Watts
	Difference: 32 Watts (213%)

Memory Bandwidth

Theoretically speaking, the GeForce 8600 GT 512MB GDDR3 will be 56% faster than the GeForce 810M overall, because of its greater data rate. (explain)

GeForce 8600 GT 512MB GDDR3		22400 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 8000 (56%)

Texel Rate

The GeForce 8600 GT 512MB GDDR3 is quite a bit (about 46%) more effective at AF than the GeForce 810M. (explain)

GeForce 8600 GT 512MB GDDR3		8640 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 2736 (46%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 8600 GT 512MB GDDR3 is superior to the GeForce 810M, and very much so. (explain)

GeForce 8600 GT 512MB GDDR3		4320 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 1368 (46%)

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 max amount of information (in units of MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling 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 the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
