Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 580 3GB is 1236% quicker than the GeForce 930M in general, because of its higher data rate. (explain)

GeForce GTX 580 3GB		192384 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 177984 (1236%)

Texel Rate

The GeForce GTX 580 3GB is quite a bit (about 122%) faster with regards to AF than the GeForce 930M. (explain)

GeForce GTX 580 3GB		49408 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 27136 (122%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 580 3GB is a better choice, by far. (explain)

GeForce GTX 580 3GB		37056 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 29632 (399%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
