Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 750 should in theory be quite a bit faster than the GeForce 920M in general. (explain)

GeForce GTX 750		80000 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 65600 (456%)

Texel Rate

The GeForce GTX 750 should be just a bit (approximately 7%) more effective at AF 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 data (counted in MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If it uses 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
