Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 380 2G should be 1040% faster than the GeForce 940M in general, due to its greater data rate. (explain)

Radeon R9 380 2G		182400 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 166400 (1040%)

Texel Rate

The Radeon R9 380 2G should be quite a bit (approximately 322%) more effective at texture filtering than the GeForce 940M. (explain)

Radeon R9 380 2G		108640 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 82912 (322%)

Pixel Rate

The Radeon R9 380 2G will be a lot (about 262%) better at FSAA than the GeForce 940M, and also should be able to handle higher resolutions while still performing well. (explain)

Radeon R9 380 2G		31040 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 22464 (262%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 number of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
