Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon R9 M280X should in theory be a small bit faster than the GeForce GTX 1050 3GB in general. (explain)

Radeon R9 M280X		88000 MB/sec
GeForce GTX 1050 3GB		86016 MB/sec
	Difference: 1984 (2%)

Texel Rate

The GeForce GTX 1050 3GB will be much (about 33%) better at texture filtering than the Radeon R9 M280X. (explain)

GeForce GTX 1050 3GB		66816 Mtexels/sec
Radeon R9 M280X		50400 Mtexels/sec
	Difference: 16416 (33%)

Pixel Rate

The GeForce GTX 1050 3GB is quite a bit (about 132%) more effective at FSAA than the Radeon R9 M280X, and will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 1050 3GB		33408 Mpixels/sec
Radeon R9 M280X		14400 Mpixels/sec
	Difference: 19008 (132%)

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 maximum amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it must 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 anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its 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 - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
