Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M 15 Watts
GeForce 8600 GT 256MB DDR2 47 Watts
Difference: 32 Watts (213%)

Memory Bandwidth

In theory, the GeForce 810M is 13% faster than the GeForce 8600 GT 256MB DDR2 overall, because of its greater data rate. (explain)

GeForce 810M 14400 MB/sec
GeForce 8600 GT 256MB DDR2 12800 MB/sec
Difference: 1600 (13%)

Texel Rate

The GeForce 8600 GT 256MB DDR2 is a lot (more or less 46%) faster with regards to anisotropic filtering than the GeForce 810M. (explain)

GeForce 8600 GT 256MB DDR2 8640 Mtexels/sec
GeForce 810M 5904 Mtexels/sec
Difference: 2736 (46%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 8600 GT 256MB DDR2 is the winner, and very much so. (explain)

GeForce 8600 GT 256MB 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.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 are applied in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
