In theory, the GeForce GTX 560 Ti 448 is 900% quicker than the GeForce 920M in general, because of its greater data rate. (explain)

GeForce GTX 560 Ti 448		144000 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 129600 (900%)

Texel Rate

The GeForce GTX 560 Ti 448 will be quite a bit (about 34%) more effective at texture filtering than the GeForce 920M. (explain)

GeForce GTX 560 Ti 448		40992 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 10464 (34%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 560 Ti 448 is a better choice, by far. (explain)

GeForce GTX 560 Ti 448		29280 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 21648 (284%)

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 (measured in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once 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, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
