Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 1050 3GB will be 19% quicker than the Radeon R9 M270X overall, because of its higher bandwidth. (explain)

GeForce GTX 1050 3GB		86016 MB/sec
Radeon R9 M270X		72000 MB/sec
	Difference: 14016 (19%)

Texel Rate

The GeForce GTX 1050 3GB is a lot (more or less 130%) better at anisotropic filtering than the Radeon R9 M270X. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
Radeon R9 M270X		29000 Mtexels/sec
	Difference: 37816 (130%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 1050 3GB is superior to the Radeon R9 M270X, and very much so. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
Radeon R9 M270X		11600 Mpixels/sec
	Difference: 21808 (188%)

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 (counted in megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated 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 fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
