Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 5700 XT 50th Anniversary Edition, in theory, should be quite a bit faster than the GeForce 940M in general. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		458752 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 442752 (2767%)

Texel Rate

The Radeon RX 5700 XT 50th Anniversary Edition should be quite a bit (approximately 945%) better at AF than the GeForce 940M. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 243072 (945%)

Pixel Rate

The Radeon RX 5700 XT 50th Anniversary Edition will be a lot (approximately 1154%) faster with regards to full screen anti-aliasing than the GeForce 940M, and should be capable of handling higher resolutions more effectively. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 98944 (1154%)

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 moved past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at 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 write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
