Radeon RX 5700 XT		458752 MB/sec
	Difference: 319795 (70%)

Texel Rate

The GeForce RTX 3080 is much (more or less 53%) faster with regards to texture filtering than the Radeon RX 5700 XT. (explain)

GeForce RTX 3080		391680 Mtexels/sec
Radeon RX 5700 XT		256800 Mtexels/sec
	Difference: 134880 (53%)

Pixel Rate

The GeForce RTX 3080 is quite a bit (more or less 35%) more effective at anti-aliasing than the Radeon RX 5700 XT, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce RTX 3080		138240 Mpixels/sec
Radeon RX 5700 XT		102720 Mpixels/sec
	Difference: 35520 (35%)

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 megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, 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 number of texture map elements (texels) that are applied per second. This figure is worked out 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 per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
