GeForce 810M vs GeForce GT 310

Intro

The GeForce 810M comes with a GPU core speed of 738 MHz, and the 1024 MB of DDR3 memory runs at 900 MHz through a 64-bit bus. It also is made up of 48 Stream Processors, 8 TAUs, and 4 ROPs.

Compare that to the GeForce GT 310, which has a GPU core clock speed of 589 MHz, and 512 MB of DDR2 memory running at 1000 MHz through a 64-bit bus. It also is comprised of 16 SPUs, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M 15 Watts
GeForce GT 310 31 Watts
Difference: 16 Watts (107%)

Memory Bandwidth

The GeForce GT 310, in theory, should perform a small bit faster than the GeForce 810M overall. (explain)

GeForce GT 310 16000 MB/sec
GeForce 810M 14400 MB/sec
Difference: 1600 (11%)

Texel Rate

The GeForce 810M should be a lot (approximately 25%) faster with regards to texture filtering than the GeForce GT 310. (explain)

GeForce 810M 5904 Mtexels/sec
GeForce GT 310 4712 Mtexels/sec
Difference: 1192 (25%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 810M is superior to the GeForce GT 310, by far. (explain)

GeForce 810M 2952 Mpixels/sec
GeForce GT 310 2356 Mpixels/sec
Difference: 596 (25%)

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 (measured in megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
