Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 480 is 1538% faster than the GeForce 940M overall, because of its higher data rate. (explain)

Radeon RX 480		262144 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 246144 (1538%)

Texel Rate

The Radeon RX 480 is much (about 527%) more effective at anisotropic filtering than the GeForce 940M. (explain)

Radeon RX 480		161280 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 135552 (527%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 480 is a better choice, by far. (explain)

Radeon RX 480		35840 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 27264 (318%)

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 data (in units of megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the 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 most pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
