Seems like every day there’s new details arriving regarding AMD’s upcoming Ryzen 3000-series processors, and the accompanying 500-series motherboards. While we know high-end X570-based motherboards are coming, new details have emerged regarding a potentially higher-end X590 chipset as well as the lower-end B550 and A520 chipsets.

AMD X590 Motherboard Chipset Name Discovered In BIOs

As reported by the German technology news site ComputerBase, the developer of the DRAM Calculater application for Ryzen processors, announced via Twitter that an “AMD X590” chipset was “coming soon.” The user, who goes by the handle @1usmus on Twitter, has since deleted the tweet.

Thankfully, that is not the only source of the information, as a ComputerBase forum member was also able to pull more hard evidence directly from the GIGABYTE BIOS files.

If there is indeed an X590 chipset in the works, it is unclear what advantages it will have over the upcoming X570 chipset. ComputerBase speculates that it may offer an increased number of PCIe 4.0 lanes, as the I/O die design that AMD uses for both Matisse (Ryzen 3000) and X570 is technically capable of outputting up to 24 PCIe lanes.

That said, all of this should be taken with a heavy dose of salt as we have no way of verifying any of this at this time.

Note from Jim: I have a good source saying, as far as they are aware at least, X590 doesn’t exist however X599 arrives in October.

ASMedia To Ship B550 and A520 Chipsets By End of the Year

Moving on to the more concrete news. A recent report by DigiTimes outlines ASMedia’s plans to fulfill orders for AMD B550 and A520 chipsets by Q4 2019, which means we could see motherboards released as early as Q1 2020.

The new chipsets will succeed AMD’s current B450 and A320 offerings at the mid-range entry-level markets, respectively. While the report does mention that these new chipsets will support PCIe 3.0, there’s no mention of support for the newer PCIe 4.0 standard. We take that to mean the chipsets themselves will likely not supply any additional PCIe 4.0 lanes, but motherboards based on them will still enable PCIe 4.0 support from the processor. However, that’s just speculation at this point.
