Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 285 1GB should perform much faster than the GeForce 930M in general. (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%) more effective 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

The GeForce GTX 285 1GB is a lot (approximately 179%) better at full screen anti-aliasing than the GeForce 930M, and will be able to handle higher resolutions without losing too much performance. (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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
