Radeon R9 Nano vs Radeon RX 5700

Intro

Compare that to the Radeon RX 5700, which makes use of a 7 nm design. AMD has clocked the core speed at 1465 MHz. The GDDR6 memory runs at a frequency of 1750 MHz on this specific card. It features 2304 SPUs as well as 144 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 Nano		175 Watts
Radeon RX 5700		180 Watts
	Difference: 5 Watts (3%)

Memory Bandwidth

The Radeon R9 Nano should theoretically perform a bit faster than the Radeon RX 5700 in general. (explain)

Radeon R9 Nano		512000 MB/sec
Radeon RX 5700		458752 MB/sec
	Difference: 53248 (12%)

Texel Rate

The Radeon R9 Nano should be a lot (about 21%) better at AF than the Radeon RX 5700. (explain)

Radeon R9 Nano		256000 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 45040 (21%)

Pixel Rate

The Radeon RX 5700 is quite a bit (more or less 47%) faster with regards to full screen anti-aliasing than the Radeon R9 Nano, and should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 5700		93760 Mpixels/sec
Radeon R9 Nano		64000 Mpixels/sec
	Difference: 29760 (47%)

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 max amount of information (measured in megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 are applied per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better 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 graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
