Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 9600 GSO 1.5GB should in theory be a lot faster than the GeForce 920M in general. (explain)

GeForce 9600 GSO 1.5GB		38400 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 24000 (167%)

Texel Rate

The GeForce 920M should be just a bit (approximately 16%) faster with regards to anisotropic filtering than the GeForce 9600 GSO 1.5GB. (explain)

GeForce 920M		30528 Mtexels/sec
GeForce 9600 GSO 1.5GB		26400 Mtexels/sec
	Difference: 4128 (16%)

Pixel Rate

If using a high resolution is important to you, then the GeForce 920M is the winner, though not by far. (explain)

GeForce 920M		7632 Mpixels/sec
GeForce 9600 GSO 1.5GB		6600 Mpixels/sec
	Difference: 1032 (16%)

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 max amount of information (measured in megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out 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 outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
