PowerColor Radeon RX 6900 XT vs XFX Radeon VII

Comparison of GPU cores for XFX Radeon VII and PowerColor Radeon RX 6900 XT graphics cards. The GPU core data contains the number of blocks (in the AMD documentation these blocks are called Shader Engine (SE), while Nvidia calls them Graphics Processing Clusters (GPC), words are different, the essence is the same) and ROP/TMUs (Raster Processing Units). These characteristics have a great influence on the GPU computing power.
