GeForce RTX 2080 vs Radeon R9 Nano

Intro

The GeForce RTX 2080 comes with a core clock speed of 1515 MHz and a GDDR6 memory speed of 14 MHz. It also features a 256-bit bus, and makes use of a 12 nm design. It is made up of 2944 SPUs, 184 TAUs, and 64 ROPs.

Compare all of that to the Radeon R9 Nano, which features a GPU core clock speed of 1000 MHz, and 4096 MB of HBM RAM set to run at 500 MHz through a 4096-bit bus. It also is made up of 4096 SPUs, 256 TAUs, and 64 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR 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 amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
