Radeon R9 Nano vs Radeon RX 5700 XT

Intro

Compare those specifications to the Radeon RX 5700 XT, which uses a 7 nm design. AMD has set the core frequency at 1605 MHz. The GDDR6 RAM runs at a frequency of 1750 MHz on this card. It features 2560 SPUs as well as 160 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 Nano		175 Watts
Radeon RX 5700 XT		225 Watts
	Difference: 50 Watts (29%)

Memory Bandwidth

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

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

Texel Rate

The Radeon RX 5700 XT is a little bit (approximately 0%) more effective at anisotropic filtering than the Radeon R9 Nano. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
Radeon R9 Nano		256000 Mtexels/sec
	Difference: 800 (0%)

Pixel Rate

The Radeon RX 5700 XT is much (approximately 61%) better at full screen anti-aliasing than the Radeon R9 Nano, and also should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Radeon R9 Nano		64000 Mpixels/sec
	Difference: 38720 (61%)

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 largest amount of data (in units of megabytes per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of 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 in one second.

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