GeForce 920M		14400 MB/sec
	Difference: 305600 (2122%)

Texel Rate

The Radeon R9 290X will be quite a bit (more or less 361%) more effective at texture filtering than the GeForce 920M. (explain)

Radeon R9 290X		140800 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 110272 (361%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 290X is a better choice, by a large margin. (explain)

Radeon R9 290X		51200 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 43568 (571%)

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

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
