Gigabyte has quietly launched two new microATX motherboards, the B450M D3HP and B450M D3HP WIFI6E, built on the eight-year-old AMD B450 chipset. They support Ryzen 3000 through Ryzen 5000 processors and APUs with DDR4 memory, giving budget builders and AM4 upgraders a cheaper alternative amid rising DDR5 prices.
Gigabyte has launched two new motherboards, the B450M D3HP and B450M D3HP WIFI6E, based on AMD's B450 chipset that originally launched back in 2018. As reported by Tom's Hardware and TechPowerUp, the move is part of a broader trend of motherboard makers reviving older DDR4-compatible platforms in response to soaring DDR5 memory prices, giving budget builders and upgraders a more affordable path forward.
Both microATX boards use a 4+2 phase power delivery design and support a wide range of AM4 processors, from Ryzen 3000 through Ryzen 5000, as well as APUs from Ryzen 3000G to Ryzen 5000G, and can handle SKUs from 35W efficiency parts up to 105W flagships like the Ryzen 9 5950X. Four DDR4 slots support up to 128GB of memory at DDR4-2667, while storage options include two M.2 2280 slots (one PCIe 3.0 x4, one PCIe 2.0 x2) and four SATA III ports for legacy drives.
Expansion is limited to a single PCIe 3.0 x16 slot for a graphics card and one PCIe 2.0 x1 slot, reflecting the board's budget positioning. Display outputs include one DisplayPort 1.2 and two HDMI 2.0b ports for those relying on integrated graphics, and connectivity covers four USB 3.2 Gen 1 ports, three USB 2.0 ports, and Gigabit Ethernet. The only real difference between the two models is that the WIFI6E variant adds Wi-Fi 6E via a Realtek RTL8852CE controller along with Bluetooth support, according to both sources.
A Q-Flash Plus button on the rear I/O allows BIOS updates without a CPU, memory, or GPU installed, which TechPowerUp notes is handy for anyone planning to drop in a new Ryzen processor. Gigabyte has not announced pricing or exact availability for either board, and neither has appeared at major retailers yet, though Tom's Hardware notes that past B450 boards typically started around $50 to $100 depending on tier.
