AMD B550 Specifications and Details

▤ Summary

Many who made the move towards a Ryzen 3000 processor, also treated themselves with an X570 motherboard for PCIe Gen 4.0 and AX WIFI. Meaning PCIe Gen 3.0 is the biggest change compared to X570. That also means the interlink between the chipset and CPU is running over four Gen 3 lanes. The good news is that with four extra Gen 4 lanes from the CPU, you can still opt to go with an M2 PCIe 4.0 slot. But lets compare the two: So compared to the top-end X570, it offers fewer USB 3.2 Gen2 (10 Gb/s) ports, does not support PCI Express 4.0, and communicates with the Ryzen processor via four PCI-E 3.0 lines (instead of PCI-E 4.0), which limits the total bandwidth controllers built into it.
