GeForce 810M vs GeForce GT 310

Intro

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

Compare those specifications to the GeForce GT 310, which features a clock frequency of 589 MHz and a DDR2 memory frequency of 1000 MHz. It also features a 64-bit bus, and uses a 40 nm design. It is made up 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

Theoretically speaking, the GeForce GT 310 is 11% quicker than the GeForce 810M overall, due to its greater bandwidth. (explain)

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

Texel Rate

The GeForce 810M should be much (more or less 25%) faster with regards to anisotropic filtering than the GeForce GT 310. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the GeForce 810M is a better choice, by a large margin. (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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 processed per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at 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 the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
