Radeon R9 Nano vs Radeon RX 5700 XT

Intro

Compare those specifications to the Radeon RX 5700 XT, which has GPU clock speed of 1605 MHz, and 8096 MB of GDDR6 RAM running at 1750 MHz through a 256-bit bus. It also is made up of 2560 SPUs, 160 Texture Address Units, and 64 Raster Operation Units.

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

Texel Rate

The Radeon RX 5700 XT will be a little bit (about 0%) faster with regards to texture 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

The Radeon RX 5700 XT will be quite a bit (approximately 61%) more effective at AA than the Radeon R9 Nano, and also capable of handling higher screen resolutions while still performing well. (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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
