GeForce GTX 980M vs Radeon RX 5700 XT

Intro

Compare all of that to the Radeon RX 5700 XT, which makes use of a 7 nm design. AMD has set the core speed at 1605 MHz. The GDDR6 memory works at a frequency of 1750 MHz on this model. It features 2560 SPUs along with 160 Texture Address Units and 64 ROPs.

GeForce GTX 980M		100 Watts
Radeon RX 5700 XT		225 Watts
	Difference: 125 Watts (125%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 XT should be quite a bit faster than the GeForce GTX 980M in general. (explain)

Radeon RX 5700 XT		458752 MB/sec
GeForce GTX 980M		128000 MB/sec
	Difference: 330752 (258%)

Texel Rate

The Radeon RX 5700 XT is a lot (about 158%) more effective at texture filtering than the GeForce GTX 980M. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
GeForce GTX 980M		99648 Mtexels/sec
	Difference: 157152 (158%)

Pixel Rate

The Radeon RX 5700 XT is quite a bit (about 55%) more effective at full screen anti-aliasing than the GeForce GTX 980M, and also will be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
GeForce GTX 980M		66432 Mpixels/sec
	Difference: 36288 (55%)

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 largest amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that can be processed per 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units 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 fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
