GeForce 940M vs Nvidia Titan Xp

Intro

Compare all of that to the Nvidia Titan Xp, which comes with core clock speeds of 1582 MHz on the GPU, and 1426 MHz on the 12288 MB of GDDR5X RAM. It features 3840 SPUs along with 240 TAUs and 96 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Nvidia Titan Xp should in theory be much superior to the GeForce 940M overall. (explain)

Nvidia Titan Xp		560845 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 544845 (3405%)

Texel Rate

The Nvidia Titan Xp should be quite a bit (more or less 1376%) faster with regards to anisotropic filtering than the GeForce 940M. (explain)

Nvidia Titan Xp		379680 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 353952 (1376%)

Pixel Rate

The Nvidia Titan Xp is a lot (approximately 1671%) more effective at AA than the GeForce 940M, and also will be able to handle higher screen resolutions better. (explain)

Nvidia Titan Xp		151872 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 143296 (1671%)

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 max amount of information (counted in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
