Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 9600 GSO 384MB should perform much faster than the GeForce 920M in general. (explain)

GeForce 9600 GSO 384MB		38400 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 24000 (167%)

Texel Rate

The GeForce 920M will be just a bit (approximately 16%) better at AF than the GeForce 9600 GSO 384MB. (explain)

GeForce 920M		30528 Mtexels/sec
GeForce 9600 GSO 384MB		26400 Mtexels/sec
	Difference: 4128 (16%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 920M is the winner, but only just. (explain)

GeForce 920M		7632 Mpixels/sec
GeForce 9600 GSO 384MB		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 largest amount of information (counted in MB per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
