Texel Rate

The GeForce 8600 GT 1GB DDR2 will be quite a bit (approximately 46%) faster with regards to AF than the GeForce 810M. (explain)

GeForce 8600 GT 1GB DDR2		8640 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 2736 (46%)

Pixel Rate

The GeForce 8600 GT 1GB DDR2 will be much (approximately 46%) more effective at anti-aliasing than the GeForce 810M, and also will be able to handle higher screen resolutions while still performing well. (explain)

GeForce 8600 GT 1GB DDR2		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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel 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 maximum fill rate.
