GeForce 940M vs Radeon RX 5700 XT

Intro

Compare those specifications to the Radeon RX 5700 XT, which has a clock frequency of 1605 MHz and a GDDR6 memory speed of 1750 MHz. It also features a 256-bit bus, and makes use of a 7 nm design. It is comprised of 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 XT is 2767% faster than the GeForce 940M overall, because of its higher bandwidth. (explain)

Radeon RX 5700 XT		458752 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 442752 (2767%)

Texel Rate

The Radeon RX 5700 XT should be quite a bit (about 898%) faster with regards to anisotropic filtering than the GeForce 940M. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 231072 (898%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 5700 XT is superior to the GeForce 940M, by far. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 94144 (1098%)

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 (measured in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 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 anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write 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 speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
