GeForce 830M vs GeForce GT 310

Intro

The GeForce 830M has clock speeds of 1029 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 256 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.

Compare all that to the GeForce GT 310, which comes with GPU clock speed of 589 MHz, and 512 MB of DDR2 RAM set to run at 1000 MHz through a 64-bit bus. It also features 16 SPUs, 8 TAUs, and 4 Raster Operation Units.

The GeForce GT 310 should theoretically be a little bit faster than the GeForce 830M in general. (explain)

GeForce GT 310 16000 MB/sec
GeForce 830M 14400 MB/sec
Difference: 1600 (11%)

Texel Rate

The GeForce 830M should be quite a bit (about 249%) more effective at AF than the GeForce GT 310. (explain)

GeForce 830M 16464 Mtexels/sec
GeForce GT 310 4712 Mtexels/sec
Difference: 11752 (249%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 830M is superior to the GeForce GT 310, by a large margin. (explain)

GeForce 830M 8232 Mpixels/sec
GeForce GT 310 2356 Mpixels/sec
Difference: 5876 (249%)

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 maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
