GeForce 810M vs GeForce GTX 850M

Intro

The GeForce 810M comes with a GPU core clock speed of 738 MHz, and the 1024 MB of DDR3 memory runs at 900 MHz through a 64-bit bus. It also features 48 SPUs, 8 TAUs, and 4 Raster Operation Units.

Compare those specs to the GeForce GTX 850M, which comes with core clock speeds of 876 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M 15 Watts
GeForce GTX 850M 40 Watts
Difference: 25 Watts (167%)

Memory Bandwidth

In theory, the GeForce GTX 850M should perform quite a bit faster than the GeForce 810M in general. (explain)

GeForce GTX 850M 32000 MB/sec
GeForce 810M 14400 MB/sec
Difference: 17600 (122%)

Texel Rate

The GeForce GTX 850M should be quite a bit (more or less 493%) better at anisotropic filtering than the GeForce 810M. (explain)

GeForce GTX 850M 35040 Mtexels/sec
GeForce 810M 5904 Mtexels/sec
Difference: 29136 (493%)

Pixel Rate

The GeForce GTX 850M should be much (about 375%) more effective at full screen anti-aliasing than the GeForce 810M, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 850M 14016 Mpixels/sec
GeForce 810M 2952 Mpixels/sec
Difference: 11064 (375%)

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 maximum amount of data (measured in MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that can be processed per second. This number is worked out 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 graphics 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 the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
