Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 260 216SP 55 nm, in theory, should be a lot faster than the GeForce 930M in general. (explain)

GeForce GTX 260 216SP 55 nm		111888 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 97488 (677%)

Texel Rate

The GeForce GTX 260 216SP 55 nm will be much (more or less 86%) faster with regards to AF than the GeForce 930M. (explain)

GeForce GTX 260 216SP 55 nm		41472 Mtexels/sec
GeForce 930M		22272 Mtexels/sec
	Difference: 19200 (86%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 260 216SP 55 nm is a better choice, and very much so. (explain)

GeForce GTX 260 216SP 55 nm		16128 Mpixels/sec
GeForce 930M		7424 Mpixels/sec
	Difference: 8704 (117%)

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 max amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it 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 anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
