GeForce RTX 2080 vs Radeon RX 6700 XT

Intro

The GeForce RTX 2080 uses a 12 nm design. nVidia has clocked the core frequency at 1515 MHz. The GDDR6 memory works at a speed of 1750 MHz on this particular model. It features 2944 SPUs along with 184 TAUs and 64 Rasterization Operator Units.

Compare all of that to the Radeon RX 6700 XT, which comes with a clock frequency of 2321 MHz and a GDDR6 memory speed of 2000 MHz. It also features a 192-bit memory bus, and uses a 7 nm design. It is made up of 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
