Radeon R9 Nano vs Radeon RX 5700

Intro

Compare those specifications to the Radeon RX 5700, which makes use of a 7 nm design. AMD has clocked the core frequency at 1465 MHz. The GDDR6 RAM runs at a frequency of 1750 MHz on this particular card. It features 2304 SPUs along with 144 Texture Address Units 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

In theory, the Radeon R9 Nano should be 12% faster than the Radeon RX 5700 in general, due to its higher bandwidth. (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%) faster with regards to texture filtering than the Radeon RX 5700. (explain)

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

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 5700 is superior to the Radeon R9 Nano, by far. (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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied 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 better 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 maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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 get to the maximum fill rate.
