Rumors of a Z390 chipset have been floating around for some time, and last month's release notes for a version of Intel's Rapid Store Technology confirmed its existence. Now, the company has made the Z390 official by posting a full product brief on its website.
The Z390 appears very similar to its Z370 predecessor. There are some new features, but these are also found in the recent 300-series chipsets--- H370, B360, Q370, H310---which Intel launched alongside its latest Coffee Lake CPUs earlier this year.
The new features include Wireless-AC 802.11 AC connectivity with gigabit throughput, thanks to the integrated Intel Wireless-AC 9560 MAC. There are also up to 6 x USB 3.1 Gen 2 Ports, 10 USB 3.1 Gen 1 (5 Gbps) ports, 14 USB 2.0 ports, support for 24 PCIe 3.0 lanes, Bluetooth 5.0, and support for RAID 0, 1, and 5 with PCIe NVMe SSDs.
German PC OEM Bluechip recently posted a roadmap suggesting that the Z390 would be unveiled at Computex and will launch in the new line of motherboards releasing in Q3. Intel's eight-core, sixteen-thread Coffee Lake-S processor is expected to arrive soon afterward in Q4.
The Z390 is expected to arrive around the same time as AMD's Z490 chipset, which will come with improved I/O capabilities over the current-gen X470 mobos.
We'll discover more about Intel's and AMD's plans at Computex, which takes place between June 5th and June 9th
