A powerful chipset, the B550 provides expansion cards and M.2 storage devices with PCIe 4.0 lanes. The only downside to using B550 chipsets is that they will run hotter than motherboards like ASUS ROG STRIX X570-I Gaming with x570 chipsets.
On the other hand, motherboards using the X570 chipset consume more power and feature active cooling. The B550 chipsets are a great mid-range gaming option and are well balanced.
