GeForce 940M		16000 MB/sec
	Difference: 304000 (1900%)

Texel Rate

The Radeon R9 290 will be much (approximately 398%) better at texture filtering than the GeForce 940M. (explain)

Radeon R9 290		128000 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 102272 (398%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 290 is the winner, by a large margin. (explain)

Radeon R9 290		51200 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 42624 (497%)

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 (counted in megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated 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 handling 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 the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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 - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
