Radeon RX 5700 XT		458752 MB/sec
	Difference: 53248 (12%)

Texel Rate

The Radeon RX 5700 XT will be a small bit (approximately 0%) faster with regards to anisotropic filtering than the Radeon R9 Nano. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
Radeon R9 Nano		256000 Mtexels/sec
	Difference: 800 (0%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 5700 XT is the winner, by far. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Radeon R9 Nano		64000 Mpixels/sec
	Difference: 38720 (61%)

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 largest amount of information (measured in MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be 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 better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
