Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M295X should be a lot faster than the GeForce 920M overall. (explain)

Radeon R9 M295X		176000 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 161600 (1122%)

Texel Rate

The Radeon R9 M295X should be much (more or less 214%) better at anisotropic filtering than the GeForce 920M. (explain)

GeForce 920M		30528 Mtexels/sec
	Difference: 65472 (214%)

Pixel Rate

The Radeon R9 M295X will be much (approximately 214%) better at anti-aliasing than the GeForce 920M, and should be capable of handling higher resolutions better. (explain)

Radeon R9 M295X		24000 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 16368 (214%)

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 (measured in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of 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 the texel rate, the better the video 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 maximum amount of pixels that 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 Raster Operations Pipelines by the clock speed of the card. 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 also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
