Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1050 3GB is 497% quicker than the GeForce 920M in general, because of its greater data rate. (explain)

GeForce GTX 1050 3GB		86016 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 71616 (497%)

Texel Rate

The GeForce GTX 1050 3GB should be much (approximately 119%) faster with regards to texture filtering than the GeForce 920M. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 36288 (119%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 1050 3GB is a better choice, and very much so. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 25776 (338%)

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 max amount of information (measured in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 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, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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 - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
