Compare any two graphics cards:

GeForce 940M vs GeForce GTX 960

Intro

The GeForce 940M comes with a GPU clock speed of 1072 MHz, and the 2048 MB of DDR3 RAM runs at 1000 MHz through a 64-bit bus. It also is made up of 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Compare that to the GeForce GTX 960, which features a clock frequency of 1127 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit memory bus, and makes use of a 28 nm design. It is comprised of 1024 SPUs, 64 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 960 should be 600% faster than the GeForce 940M overall, because of its greater data rate. (explain)

GeForce GTX 960		112000 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 96000 (600%)

Texel Rate

The GeForce GTX 960 should be a lot (approximately 180%) faster with regards to texture filtering than the GeForce 940M. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 46400 (180%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 960 is the winner, by far. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 27488 (321%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
