Radeon R9 Nano vs Radeon RX 560

Intro

Compare those specs to the Radeon RX 560, which uses a 14 nm design. AMD has clocked the core frequency at 1175 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this card. It features 1024 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
Radeon R9 Nano		175 Watts
	Difference: 95 Watts (119%)

Memory Bandwidth

Performance-wise, the Radeon R9 Nano should theoretically be much superior to the Radeon RX 560 overall. (explain)

Radeon R9 Nano		512000 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 397312 (346%)

Texel Rate

The Radeon R9 Nano is quite a bit (more or less 240%) faster with regards to texture filtering than the Radeon RX 560. (explain)

Radeon R9 Nano		256000 Mtexels/sec
Radeon RX 560		75200 Mtexels/sec
	Difference: 180800 (240%)

Pixel Rate

The Radeon R9 Nano is a lot (about 240%) better at FSAA than the Radeon RX 560, and also capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon R9 Nano		64000 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 45200 (240%)

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 data (measured in MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
