Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce 9600 GT 1GB should theoretically be quite a bit superior to the GeForce 920M overall. (explain)

GeForce 9600 GT 1GB		57600 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 43200 (300%)

Texel Rate

The GeForce 920M is much (approximately 47%) more effective at anisotropic filtering than the GeForce 9600 GT 1GB. (explain)

GeForce 920M		30528 Mtexels/sec
GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 9728 (47%)

Pixel Rate

The GeForce 9600 GT 1GB should be much (approximately 36%) better at anti-aliasing than the GeForce 920M, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce 9600 GT 1GB		10400 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 2768 (36%)

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 maximum amount of data (measured in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 higher 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 amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs 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 fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
