Mainstream motherboards for AMD 3rd Gen Ryzen might be delayed until the end of the year, according to a new, rather convoluted, report. Insider sources seem to suggest that ASMedia has managed to keep hold of all mainstream PCH orders for AMD’s 500-series motherboard platform, however, the tech company won’t complete relevant PCIe 4.0 solutions until the end of 2019.

AMD is reportedly ditching ASMedia for enthusiast X570 chipset production, instead returning to its ATI roots and designing the platform controller hub itself. However, recent reports suggest AMD may have had no option but to design the enthusiast PCH in-house for its mid-year 3rd Gen Ryzen release window if it hoped to keep the PCIe 4.0 dream alive, due to a lack of PCIe 4.0 compliant product over at chipset partners, ASMedia.

Speaking to DigiTimes, insider sources say the long-standing contract between AMD and ASMedia to produce chipsets – which has existed for both the 300- and 400-series motherboards – is still in place for 500-series motherboards, barring the X570 chipset, which AMD is designing itself.
