GeForce 940M vs GeForce GTX Titan X

Intro

Compare those specs to the GeForce GTX Titan X, which comes with a clock frequency of 1000 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 384-bit bus, and makes use of a 28 nm design. It is comprised of 3072 SPUs, 192 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX Titan X should theoretically perform quite a bit faster than the GeForce 940M overall. (explain)

GeForce GTX Titan X		336000 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 320000 (2000%)

Texel Rate

The GeForce GTX Titan X should be much (about 646%) better at 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 high levels of AA is important to you, then the GeForce GTX Titan X is superior to the GeForce 940M, and very much so. (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 max amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 are processed per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, 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 could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
