GeForce 920M		14400 MB/sec
	Difference: 72000 (500%)

Texel Rate

The GeForce GTX 750 Ti should be quite a bit (approximately 34%) faster with regards to anisotropic filtering than the GeForce 920M. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 10272 (34%)

Pixel Rate

The GeForce GTX 750 Ti should be much (about 114%) faster with regards to full screen anti-aliasing than the GeForce 920M, and should be capable of handling higher resolutions better. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 8688 (114%)

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 MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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