Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 1050 3GB should be 19% faster than the Radeon R9 M270X overall, due to its greater 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 will be quite a bit (more or less 130%) faster with regards to AF 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 resolution is important to you, then the GeForce GTX 1050 3GB is the winner, 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 max amount of information (in units of megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its 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 - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
