GeForce 940M vs Radeon RX 5600 XT

Intro

Compare those specifications to the Radeon RX 5600 XT, which has core speeds of 1375 MHz on the GPU, and 1500 MHz on the 6144 MB of GDDR6 RAM. It features 2304 SPUs as well as 144 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 5600 XT will be 2050% faster than the GeForce 940M in general, because of its higher bandwidth. (explain)

Radeon RX 5600 XT		344064 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 328064 (2050%)

Texel Rate

The Radeon RX 5600 XT is much (approximately 670%) better at anisotropic filtering than the GeForce 940M. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 172272 (670%)

Pixel Rate

The Radeon RX 5600 XT will be quite a bit (about 926%) better at anti-aliasing than the GeForce 940M, and capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 79424 (926%)

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 information (in units of MB per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core 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 processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
