Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 285 1GB is 1004% faster than the GeForce 930M overall, due to its higher data rate. (explain)

GeForce GTX 285 1GB		158976 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 144576 (1004%)

Texel Rate

The GeForce GTX 285 1GB is a lot (more or less 133%) better at anisotropic filtering than the GeForce 930M. (explain)

GeForce GTX 285 1GB		51840 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 29568 (133%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 285 1GB is a better choice, by far. (explain)

GeForce GTX 285 1GB		20736 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 13312 (179%)

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 information (measured in megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the 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 that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
