GeForce RTX 2080 vs Radeon R9 Nano

Intro

The GeForce RTX 2080 makes use of a 12 nm design. nVidia has clocked the core speed at 1515 MHz. The GDDR6 RAM runs at a speed of 14 MHz on this particular model. It features 2944 SPUs along with 184 Texture Address Units and 64 ROPs.

Compare all of that to the Radeon R9 Nano, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The HBM memory runs at a speed of 500 MHz on this card. It features 4096 SPUs as well as 256 Texture Address Units and 64 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should 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 AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
