GeForce 940M vs GeForce GTX Titan X

Intro

Compare that to the GeForce GTX Titan X, which features a clock speed of 1000 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 384-bit bus, and uses a 28 nm design. It is made up of 3072 SPUs, 192 Texture Address Units, and 96 Raster Operation Units.

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

Texel Rate

The GeForce GTX Titan X is quite a bit (about 646%) faster with regards to anisotropic filtering than the GeForce 940M. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX Titan X is a better choice, 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: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once 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 per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
