Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 550 is 617% faster than the GeForce 940M in general, because of its greater bandwidth. (explain)

Radeon RX 550		114688 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 98688 (617%)

Texel Rate

The Radeon RX 550 will be quite a bit (about 37%) better at texture filtering than the GeForce 940M. (explain)

Radeon RX 550		35200 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 9472 (37%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 550 is a better choice, by far. (explain)

Radeon RX 550		17600 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 9024 (105%)

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 data (counted in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of 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.
