GeForce RTX 2080 vs Radeon RX 6800

Intro

The GeForce RTX 2080 features a clock frequency of 1515 MHz and a GDDR6 memory speed of 1750 MHz. It also features a 256-bit bus, and uses a 12 nm design. It is comprised of 2944 SPUs, 184 Texture Address Units, and 64 ROPs.

Compare those specs to the Radeon RX 6800, which has a GPU core clock speed of 1700 MHz, and 16384 MB of GDDR6 RAM running at 2000 MHz through a 256-bit bus. It also is comprised of 3840 Stream Processors, 240 TAUs, and 96 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 processed per 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 better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends 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 maximum fill rate.
