Sources at ASUS cited by VideoCardz say that the company is working on at least two motherboards for the X590 chipset. We actually heard about the X590 chipset before the Ryzen 3000 series launch. According to many rumors it is said to offer a much higher number of PCI-Express 4.0 lanes compared to the X570 chipset.
ASUS internal documents show two motherboards appearing with X570 in their name, they include the PRIME X590-PRO and ROG STRIX X590-E. They boards are named similarly to the already released PRIME X570-PRO and ROG STRIX X570-E Gaming. Sadly, not much more is known than that. This more or less confirms that these boards exist, but we do not know if they will ever be released. As we talked about before maybe X590 is being prepared for the 16-core Ryzen 9 3950X launch, which is coming in September.
VideoCardz has also received details that ASUS is preparing a ZENITH II EXTREME. If you remember the original ZENITH was based on the X399 chipset for Threadripper processors, so the new board should feature the X599 chipset for AMD’s upcoming Threadripper 3000 series.
