GeForce GTX 980M vs Radeon RX 5600 XT

Intro

Compare those specs to the Radeon RX 5600 XT, which uses a 7 nm design. AMD has set the core speed at 1375 MHz. The GDDR6 RAM runs at a frequency of 1500 MHz on this particular model. It features 2304 SPUs along with 144 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 980M		100 Watts
Radeon RX 5600 XT		160 Watts
	Difference: 60 Watts (60%)

Memory Bandwidth

In theory, the Radeon RX 5600 XT will be 169% faster than the GeForce GTX 980M in general, due to its greater bandwidth. (explain)

Radeon RX 5600 XT		344064 MB/sec
GeForce GTX 980M		128000 MB/sec
	Difference: 216064 (169%)

Texel Rate

The Radeon RX 5600 XT is quite a bit (approximately 99%) better at AF than the GeForce GTX 980M. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
GeForce GTX 980M		99648 Mtexels/sec
	Difference: 98352 (99%)

Pixel Rate

The Radeon RX 5600 XT will be quite a bit (about 32%) more effective at anti-aliasing than the GeForce GTX 980M, and also should be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
GeForce GTX 980M		66432 Mpixels/sec
	Difference: 21568 (32%)

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 max amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
