GeForce 810M vs GeForce 8600 GT 256MB DDR2

Intro

The GeForce 810M comes with a clock frequency of 738 MHz and a DDR3 memory speed of 900 MHz. It also uses a 64-bit bus, and uses a 28 nm design. It is made up of 48 SPUs, 8 TAUs, and 4 Raster Operation Units.

Compare those specs to the GeForce 8600 GT 256MB DDR2, which features core speeds of 540 MHz on the GPU, and 400 MHz on the 256 MB of DDR2 memory. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.

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

As far as performance goes, the GeForce 810M should theoretically be a small bit superior to the GeForce 8600 GT 256MB DDR2 overall. (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 should be a lot (more or less 46%) better at 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 using lots of anti-aliasing is important to you, then the GeForce 8600 GT 256MB DDR2 is a better choice, 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: Bandwidth is the max amount of information (counted in MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once 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 texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, 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 number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
