Radeon RX 5500 vs Radeon RX 6800 XT

Intro

The Radeon RX 5500 features a GPU clock speed of 1670 MHz, and the 4096 MB of GDDR6 RAM runs at 1750 MHz through a 128-bit bus. It also features 1408 SPUs, 88 Texture Address Units, and 32 ROPs.

Compare those specifications to the Radeon RX 6800 XT, which features core speeds of 1825 MHz on the GPU, and 2000 MHz on the 16384 MB of GDDR6 memory. It features 4608 SPUs along with 288 TAUs and 128 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, 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 maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
