The company probably wants the two to have some time in the Sun before they’re joined by the more affordable B850, which gamers could be drawn to. The AMD B850 has mostly identical platform I/O to the AMD X870, except Gen 5 support for the PCI-Express x16 slot is optional (motherboard vendors can choose to wire this out as Gen 4). The 40 Gbps USB4 is also optional here. You still get CPU overclocking support. The B840 is an entry-level chipset that’s being launched to probably phase out the A620 and A620A, since it features similar I/O features to the A620A, but will probably come with drop-in compatibility for 65 W Socket AM5 processors. A deferred launch of the mid-tier chipset isn’t too off character for AMD. It launched its popular B450 and B550 chipsets several months after the X470 and X570, respectively.
Launch of AMD B850 and B840 Chipsets Pushed to Q1-2025
AMD has reportedly pushed the launch of mid-tier models from its AMD 800-series chipset to early 2025, reports ComputerBase.de. With the Ryzen 9000-series “Zen 5” processors already launched earlier this month, and compatible with existing AMD 600-series chipset motherboards with a BIOS update, motherboard vendors are leisurely announcing their motherboards based on the AMD X870E and AMD X870 chipsets. Motherboards based on both offer drop-in compatibility with Ryzen 9000-series processors, and introduce new connectivity features such as 40 Gbps USB4 and Wi-Fi 7.
