Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 250 is 360% quicker than the GeForce 940M overall, due to its greater bandwidth. (explain)

Radeon R7 250		73600 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 57600 (360%)

Texel Rate

The GeForce 940M is just a bit (more or less 7%) faster with regards to anisotropic filtering than the Radeon R7 250. (explain)

GeForce 940M		25728 Mtexels/sec
Radeon R7 250		24000 Mtexels/sec
	Difference: 1728 (7%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 940M is a better choice, but only just. (explain)

GeForce 940M		8576 Mpixels/sec
Radeon R7 250		8000 Mpixels/sec
	Difference: 576 (7%)

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 information (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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