GeForce 930M vs GeForce GT 310

Intro

Compare those specifications to the GeForce GT 310, which has a GPU core clock speed of 589 MHz, and 512 MB of DDR2 RAM set to run at 1000 MHz through a 64-bit bus. It also is comprised of 16 Stream Processors, 8 Texture Address Units, 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 quite a bit (more or less 373%) more effective at AF 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 lots of anti-aliasing is important to you, then the GeForce 930M is superior to the GeForce GT 310, by far. (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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (in units of MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 maximum number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out 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 outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
