Radeon R9 Nano vs Radeon RX 5700

Intro

The Radeon R9 Nano makes use of 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 model. It features 4096 SPUs along with 256 Texture Address Units and 64 Rasterization Operator Units.

Compare those specs to the Radeon RX 5700, which has a GPU core clock speed of 1465 MHz, and 8096 MB of GDDR6 RAM set to run at 14000 MHz through a 256-bit bus. It also is comprised of 2304 SPUs, 144 TAUs, and 64 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

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