Radeon R9 Nano vs Radeon RX 5500 XT

Intro

Compare all of that to the Radeon RX 5500 XT, which comes with core speeds of 1717 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 memory. It features 1408 SPUs along with 88 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT		130 Watts
Radeon R9 Nano		175 Watts
	Difference: 45 Watts (35%)

Memory Bandwidth

In theory, the Radeon R9 Nano is 123% faster than the Radeon RX 5500 XT in general, because of its higher bandwidth. (explain)

Radeon R9 Nano		512000 MB/sec
Radeon RX 5500 XT		229376 MB/sec
	Difference: 282624 (123%)

Texel Rate

The Radeon R9 Nano should be a lot (approximately 69%) faster with regards to anisotropic filtering than the Radeon RX 5500 XT. (explain)

Radeon R9 Nano		256000 Mtexels/sec
Radeon RX 5500 XT		151096 Mtexels/sec
	Difference: 104904 (69%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R9 Nano is superior to the Radeon RX 5500 XT, but not by far. (explain)

Radeon R9 Nano		64000 Mpixels/sec
Radeon RX 5500 XT		54944 Mpixels/sec
	Difference: 9056 (16%)

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 (in units of MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
