It has been a rumor for quite some time now, ASMedia fabricating a chipset for AMD Ryzen setups. As it seems, that now has been confirmed by motherboard manufacturers at CES, it's likely starting with the release of ZEN3 though.

And that news is going to be interesting, as it'll be a completely new chipset as ASMedia does not even have a Series 500 chipset available. The lads from Computerbase more or less confirmed this info with motherboard manufacturers, however additional news is coming from the Asia regions as a new chipset would be launched for AMD's new platform, and that would be the series 600 chipset for AMD's Ryzen 4000 processors based on Zen 3.

What exactly the portfolio looks like at the end of the year remains a rumor, as well as the features and specification of a new AMD chipset, fabricated by ASMedia.

Update - this just came in from DigiTimes:

ASMedia Technology has reportedly secured orders for AMD's 500- and 600-series chipsets, which will buoy the Taiwan-based chipmaker's sales performance in 2020 and 2021, according to industry sources.

AMD's 600-series chipsets are scheduled to be released at the end of 2020. Although ASMedia has not obtained orders for AMD's X570 chipsets that supports PCIe Gen 4, the chipmaker continues to be the maker of AMD's B550 and A520 chipsets, the sources said.

In addition to its partnership with AMD, ASMedia's USB 3.2 Gen 2x2 controller chip that supports transmission speeds up to 20Gbps is also expected to see rising demand as the chip integrated in Intel's existing CPUs can only support USB 3.2 Gen 2 that features a maximum transmission speed of 10Gbps, the sources said. ASMedia has also begun development of a USB 4 controller chip, which is set to be released in 2020, and is expected to obtain orders from PC and motherboard brands. The US-China trade war has also sent some clients shifting orders to ASMedia for packet conversion ICs and USB 3.2 host controller chips for server CPUs, and these orders' contribution to ASMedia's revenues is also expected to gradually pick up over the next three years.
