GeForce 920M		14400 MB/sec
	Difference: 65600 (456%)

Texel Rate

The GeForce GTX 750 will be a small bit (approximately 7%) faster with regards to anisotropic filtering than the GeForce 920M. (explain)

GeForce GTX 750		32640 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 2112 (7%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 750 is a better choice, by a large margin. (explain)

GeForce GTX 750		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: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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