AMD’s New B550 and A520 Motherboards Will Only Support PCIe 3.0

DigiTimes has learned that ASMedia has landed orders for B550 and A520 chipsets, which will ship to motherboard makers in Q4 2019. These will not support PCIe 4.0.

Some speculate there may be limited support (e.g., from the CPU), but only PCIe 3.0 is mentioned in the report.

That’s not surprising, as ASMedia doesn’t have a contract with AMD yet for X570. The company expects to win orders for the PCIe 4.0-based chipset in 2020.

At a recent shareholders meeting, ASMedia chairman Jerry Shen said his company will step up the development of next-generation PCIe chip products and offer complete USB solutions covering 5G, 10G, and 20G, in addition to developing more applications for its SATA controller chips.
