GeForce RTX 2080 vs Radeon R9 380 2G

Intro

The GeForce RTX 2080 has a core clock frequency of 1515 MHz and a GDDR6 memory frequency of 14 MHz. It also uses a 256-bit bus, and makes use of a 12 nm design. It features 2944 SPUs, 184 Texture Address Units, and 64 Raster Operation Units.

Compare all of that to the Radeon R9 380 2G, which comes with GPU core speed of 970 MHz, and 2048 MB of GDDR5 memory set to run at 1425 MHz through a 256-bit bus. It also is made up of 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If 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 texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
