Radeon RX 5500 XT vs Radeon RX 6800 XT
Intro
The Radeon RX 5500 XT has a clock frequency of 1717 MHz and a GDDR6 memory speed of 1750 MHz. It also features a 128-bit memory bus, and makes use of a 7 nm design. It is comprised of 1408 SPUs, 88 TAUs, and 32 ROPs.Compare those specifications to the Radeon RX 6800 XT, which uses a 7 nm design. AMD has set the core frequency at 1825 MHz. The GDDR6 RAM is set to run at a frequency of 2000 MHz on this model. It features 4608 SPUs along with 288 Texture Address Units and 128 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
