GeForce 930M vs GeForce GT 310

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 310 should be 11% quicker than the GeForce 930M in general, due to its greater data rate. (explain)

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

Texel Rate

The GeForce 930M is much (more or less 373%) more effective at anisotropic 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 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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 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 higher screen resolutions.

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

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