Radeon R9 380X vs Radeon RX 5500 XT

Intro

The Radeon R9 380X makes use of a 28 nm design. AMD has clocked the core frequency at 970 MHz. The GDDR5 memory runs at a speed of 1425 MHz on this card. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Compare all of that to the Radeon RX 5500 XT, which features a clock frequency of 1717 MHz and a GDDR6 memory speed of 1750 MHz. It also makes use of a 128-bit bus, and uses a 7 nm design. It is made up of 1408 SPUs, 88 Texture Address Units, and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
