GeForce RTX 2080 SUPER vs Radeon RX 6800 XT

Intro

The GeForce RTX 2080 SUPER comes with clock speeds of 1650 MHz on the GPU, and 1937 MHz on the 8192 MB of GDDR6 RAM. It features 3072 SPUs as well as 192 TAUs and 64 ROPs.

Compare those specs to the Radeon RX 6800 XT, which has a GPU core clock speed of 1825 MHz, and 16384 MB of GDDR6 memory set to run at 2000 MHz through a 256-bit bus. It also is made up of 4608 Stream Processors, 288 TAUs, and 128 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units by the core 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
