Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M370X should in theory be quite a bit better than the GeForce 920M overall. (explain)

Radeon R9 M370X		72000 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 57600 (400%)

Texel Rate

The Radeon R9 M370X will be a bit (approximately 5%) faster with regards to anisotropic filtering than the GeForce 920M. (explain)

Radeon R9 M370X		32000 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 1472 (5%)

Pixel Rate

The Radeon R9 M370X is much (about 68%) better at anti-aliasing than the GeForce 920M, and also will be able to handle higher screen resolutions better. (explain)

Radeon R9 M370X		12800 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 5168 (68%)

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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
