GeForce 940M vs GeForce GTX Titan X

Intro

Compare that to the GeForce GTX Titan X, which makes use of a 28 nm design. nVidia has set the core frequency at 1000 MHz. The GDDR5 memory is set to run at a speed of 1750 MHz on this card. It features 3072 SPUs along with 192 TAUs and 96 ROPs.

GeForce 940M		16000 MB/sec
	Difference: 320000 (2000%)

Texel Rate

The GeForce GTX Titan X should be much (about 646%) faster with regards to texture filtering than the GeForce 940M. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 166272 (646%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX Titan X is the winner, by far. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 87424 (1019%)

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 largest amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
