GeForce 930M vs GeForce GT 310

Intro

The GeForce 930M features a clock speed of 928 MHz and a DDR3 memory frequency of 900 MHz. It also makes use of a 64-bit bus, and makes use of a 28 nm design. It features 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GT 310 should theoretically be just a bit better 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 should be a lot (approximately 373%) more effective 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 using a high resolution is important to you, then the GeForce 930M is superior to the GeForce GT 310, and very much so. (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: Bandwidth is the max amount of data (in units of MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
