GeForce 920M		14400 MB/sec
	Difference: 163008 (1132%)

Texel Rate

The GeForce GTX 480 will be quite a bit (approximately 38%) better at texture filtering than the GeForce 920M. (explain)

GeForce GTX 480		42000 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 11472 (38%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 480 is superior to the GeForce 920M, and very much so. (explain)

GeForce GTX 480		33600 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 25968 (340%)

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 data (measured in megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of 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 amount 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 fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
