Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 9600 GSO ASUS 512 should be 11% faster than the GeForce 920M in general, because of its higher bandwidth. (explain)

GeForce 9600 GSO ASUS 512		16000 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The GeForce 920M should be a little bit (about 16%) faster with regards to AF than the GeForce 9600 GSO ASUS 512. (explain)

GeForce 920M		30528 Mtexels/sec
GeForce 9600 GSO ASUS 512		26400 Mtexels/sec
	Difference: 4128 (16%)

Pixel Rate

The GeForce 920M is just a bit (more or less 16%) faster with regards to AA than the GeForce 9600 GSO ASUS 512, and also should be able to handle higher screen resolutions while still performing well. (explain)

GeForce 920M		7632 Mpixels/sec
GeForce 9600 GSO ASUS 512		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 maximum amount of information (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 applied in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
