Radeon RX 5500 XT vs Radeon RX 7900 XTX
Intro
The Radeon RX 5500 XT comes with a core clock frequency of 1717 MHz and a GDDR6 memory frequency of 1750 MHz. It also uses a 128-bit bus, and uses a 7 nm design. It features 1408 SPUs, 88 Texture Address Units, and 32 ROPs.Compare all of that to the Radeon RX 7900 XTX, which has core speeds of 1855 MHz on the GPU, and 2500 MHz on the 24576 MB of GDDR6 memory. It features 6144 SPUs along with 384 Texture Address Units and 192 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 are processed per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. 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 quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
