GeForce 940M vs GeForce RTX 2060

Intro

Compare all of that to the GeForce RTX 2060, which comes with a GPU core clock speed of 1365 MHz, and 6144 MB of GDDR6 memory running at 1750 MHz through a 192-bit bus. It also is made up of 1920 SPUs, 120 TAUs, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce RTX 2060 will be 2050% faster than the GeForce 940M overall, due to its greater bandwidth. (explain)

GeForce RTX 2060		344064 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 328064 (2050%)

Texel Rate

The GeForce RTX 2060 should be much (approximately 537%) better at anisotropic filtering than the GeForce 940M. (explain)

GeForce RTX 2060		163800 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 138072 (537%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 2060 is the winner, and very much so. (explain)

GeForce RTX 2060		65520 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 56944 (664%)

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 (in units of MB per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units of the card by the core 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip 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 colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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 ability to reach the max fill rate.
