Radeon R9 Nano vs Radeon RX 5700 XT

Intro

The Radeon R9 Nano comes with a GPU core speed of 1000 MHz, and the 4096 MB of HBM RAM runs at 500 MHz through a 4096-bit bus. It also is made up of 4096 SPUs, 256 Texture Address Units, and 64 Raster Operation Units.

Compare all that to the Radeon RX 5700 XT, which has a core clock frequency of 1605 MHz and a GDDR6 memory speed of 14000 MHz. It also uses a 256-bit memory bus, and uses a 7 nm design. It is made up of 2560 SPUs, 160 TAUs, and 64 ROPs.

Radeon R9 Nano 256000 Mtexels/sec
Difference: 800 (0%)

Pixel Rate

The Radeon RX 5700 XT should be much (approximately 61%) better at full screen anti-aliasing than the Radeon R9 Nano, and also should be able to handle higher resolutions while still performing well. (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.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 can be processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

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