Radeon R9 Nano vs Radeon RX 5700 XT 50th Anniversary Edition

Intro

Compare all of that to the Radeon RX 5700 XT 50th Anniversary Edition, which uses a 7 nm design. AMD has set the core speed at 1680 MHz. The GDDR6 memory is set to run at a speed of 1750 MHz on this specific card. It features 2560 SPUs as well as 160 Texture Address Units and 64 ROPs.

Radeon R9 Nano		175 Watts
Radeon RX 5700 XT 50th Anniversary Edition		235 Watts
	Difference: 60 Watts (34%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 Nano is 12% quicker than the Radeon RX 5700 XT 50th Anniversary Edition in general, due to its higher bandwidth. (explain)

Radeon R9 Nano		512000 MB/sec
Radeon RX 5700 XT 50th Anniversary Edition		458752 MB/sec
	Difference: 53248 (12%)

Texel Rate

The Radeon RX 5700 XT 50th Anniversary Edition should be a small bit (about 5%) better at texture filtering than the Radeon R9 Nano. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
Radeon R9 Nano		256000 Mtexels/sec
	Difference: 12800 (5%)

Pixel Rate

The Radeon RX 5700 XT 50th Anniversary Edition is a lot (about 68%) faster with regards to anti-aliasing than the Radeon R9 Nano, and should be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
Radeon R9 Nano		64000 Mpixels/sec
	Difference: 43520 (68%)

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 information (in units of MB per second) that can be transferred over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, 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 amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of 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 output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
