Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 960 should be 678% faster than the GeForce 920M overall, because of its higher data rate. (explain)

GeForce GTX 960		112000 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 97600 (678%)

Texel Rate

The GeForce GTX 960 is much (approximately 136%) better at AF than the GeForce 920M. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 41600 (136%)

Pixel Rate

The GeForce GTX 960 will be quite a bit (approximately 373%) better at FSAA than the GeForce 920M, and also will be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 28432 (373%)

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 information (counted in megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling 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 its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
