The Gigabyte B450 Gaming X is a full-size ATX board for AMD's AM4 socket, built around the older B450 chipset. It takes Ryzen 3 through Ryzen 9 and Athlon chips, has four DDR4 slots rated to 2933 MHz, one M.2 slot and two PCIe x16 slots with CrossFire support. It is a budget-minded pick for a first build or a rebuild of an older Ryzen system. Against newer B550 boards it gives up PCIe 4.0, a second M.2 slot and USB-C, so it suits DDR4-era builds rather than new high-end ones.

Owners of this class of B450 board generally find it a solid, no-frills base for a mid-range Ryzen build. Common complaints center on the older chipset limits and the single M.2 slot rather than on reliability.
