Radeon RX 5700 XT 50th Anniversary Edition vs Radeon RX 6800 XT

Intro

The Radeon RX 5700 XT 50th Anniversary Edition has a core clock speed of 1680 MHz and a GDDR6 memory frequency of 1750 MHz. It also makes use of a 256-bit memory bus, and makes use of a 7 nm design. It is made up of 2560 SPUs, 160 TAUs, and 64 Raster Operation Units.

Compare all that to the Radeon RX 6800 XT, which features clock speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 memory. It features 4608 SPUs as well as 288 Texture Address Units and 128 Rasterization Operator Units.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines 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 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 max fill rate.
