Radeon R9 Nano vs Radeon RX 5700

Intro

The Radeon R9 Nano uses a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The HBM RAM works at a speed of 500 MHz on this card. It features 4096 SPUs as well as 256 TAUs and 64 Rasterization Operator Units.

Compare that to the Radeon RX 5700, which features clock speeds of 1465 MHz on the GPU, and 14000 MHz on the 8096 MB of GDDR6 memory. It features 2304 SPUs as well as 144 Texture Address Units and 64 Rasterization Operator Units.

Radeon RX 5700 458752 MB/sec
Difference: 53248 (12%)

Texel Rate

The Radeon R9 Nano will be a lot (more or less 21%) better at 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 using 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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (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 interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range 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 clock 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 one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on 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 potential to get to the maximum fill rate.
