VS

GeForce 930M vs GeForce GT 310

Intro

The GeForce 930M has core speeds of 928 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 memory. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Compare that to the GeForce GT 310, which has a clock speed of 589 MHz and a DDR2 memory speed of 1000 MHz. It also uses a 64-bit bus, and makes use of a 40 nm design. It features 16 SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GT 310, in theory, should be just a bit faster than the GeForce 930M in general. (explain)

GeForce GT 310 16000 MB/sec
GeForce 930M 14400 MB/sec
Difference: 1600 (11%)

Texel Rate

The GeForce 930M will be quite a bit (more or less 373%) better at texture filtering than the GeForce GT 310. (explain)

GeForce 930M 22272 Mtexels/sec
GeForce GT 310 4712 Mtexels/sec
Difference: 17560 (373%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 930M is superior to the GeForce GT 310, by a large margin. (explain)

GeForce 930M 7424 Mpixels/sec
GeForce GT 310 2356 Mpixels/sec
Difference: 5068 (215%)

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 (in units of megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the bus width by its memory 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 memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
