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 running at 1000 MHz through a 64-bit bus. It also is comprised of 16 Stream Processors, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 310 will be 11% faster than the GeForce 930M in general, due to its higher bandwidth. (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%) faster with regards to anisotropic filtering than the GeForce GT 310. (explain)

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

Pixel Rate

The GeForce 930M will be quite a bit (more or less 215%) faster with regards to FSAA than the GeForce GT 310, and also will be capable of handling higher resolutions while still performing well. (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 maximum amount of data (measured in megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
