Radeon R9 Nano vs Radeon RX 5500

Intro

Compare those specifications to the Radeon RX 5500, which makes use of a 7 nm design. AMD has clocked the core speed at 1670 MHz. The GDDR6 memory works at a speed of 1750 MHz on this card. It features 1408 SPUs along with 88 Texture Address Units and 32 Rasterization Operator Units.

Radeon RX 5500		146960 Mtexels/sec
	Difference: 109040 (74%)

Pixel Rate

The Radeon R9 Nano is a bit (approximately 20%) more effective at AA than the Radeon RX 5500, and also will be able to handle higher resolutions more effectively. (explain)

Radeon R9 Nano		64000 Mpixels/sec
Radeon RX 5500		53440 Mpixels/sec
	Difference: 10560 (20%)

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 megabytes per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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