GeForce 810M vs GeForce GT 310

Intro

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

Compare those specifications to the GeForce GT 310, which comes with a clock speed of 589 MHz and a DDR2 memory speed of 1000 MHz. It also features a 64-bit memory bus, and makes use of a 40 nm design. It is comprised of 16 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

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

Pixel Rate

The GeForce 810M is much (about 25%) better at full screen anti-aliasing than the GeForce GT 310, and also capable of handling higher screen resolutions without slowing down too much. (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 (counted in MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount 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 better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. 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 rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
