Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M395X should theoretically perform a lot faster than the GeForce 920M overall. (explain)

Radeon R9 M395X		160000 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 145600 (1011%)

Texel Rate

The Radeon R9 M395X will be a lot (more or less 203%) faster with regards to texture filtering than the GeForce 920M. (explain)

Radeon R9 M395X		92544 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 62016 (203%)

Pixel Rate

The Radeon R9 M395X should be quite a bit (about 203%) better at anti-aliasing than the GeForce 920M, and capable of handling higher resolutions while still performing well. (explain)

Radeon R9 M395X		23136 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 15504 (203%)

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 max amount of information (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 can be applied per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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