Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the GeForce GTX 970M should be a small bit faster than the GeForce GTX 1050 3GB in general. (explain)

GeForce GTX 970M		96000 MB/sec
GeForce GTX 1050 3GB		86016 MB/sec
	Difference: 9984 (12%)

Texel Rate

The GeForce GTX 970M is just a bit (about 11%) faster with regards to texture filtering than the GeForce GTX 1050 3GB. (explain)

GeForce GTX 970M		73920 Mtexels/sec
GeForce GTX 1050 3GB		66816 Mtexels/sec
	Difference: 7104 (11%)

Pixel Rate

The GeForce GTX 970M is a lot (approximately 33%) more effective at FSAA than the GeForce GTX 1050 3GB, and able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 970M		44352 Mpixels/sec
GeForce GTX 1050 3GB		33408 Mpixels/sec
	Difference: 10944 (33%)

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 over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range 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 texture units 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 amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
