Radeon R9 Nano vs Radeon RX 5700

Intro

The Radeon R9 Nano uses a 28 nm design. AMD has clocked the core speed at 1000 MHz. The HBM memory works at a speed of 500 MHz on this specific model. It features 4096 SPUs as well as 256 Texture Address Units and 64 ROPs.

Compare those specifications to the Radeon RX 5700, which uses a 7 nm design. AMD has clocked the core frequency at 1465 MHz. The GDDR6 RAM is set to run at a speed of 1750 MHz on this particular model. It features 2304 SPUs along with 144 Texture Address Units and 64 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated 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 in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few 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.
