There was a leaked Intel roadmap for 2018 which showed optimized chipsets for Coffee Lake CPUs- the H370, B360 and the H310. Intel also listed its Z390 chipset next to the Z370 chipset in its roadmap, but its purpose wasn’t clear and its release time was supposed to be for the second half of 2018. But interestingly, there is a SiSOFT database listing an Intel Z390 chipset motherboard SuperMicro C7Z390-PGW.
Mystery Six-Core CPU or incorrect detection?
There’s also an unknown Intel CPU with 6-core 12 threads with a 92-watt TDP. With an exception to its TDP, it is practically the Core i7-8700K with 95-watt TDP.
Purpose of the Z390 chipset!
Why would Intel need to have a new set of Coffee Lake motherboard chipsets and work with a brand new one? Intel has the Z390 probably to provide full support for eight-core Coffee Lake CPUs which will launch in the year 2018, bringing some head-to-head competition to AMD Ryzen’s eight core variants. It is uncertain at this point if Intel Z370 chipsets could support an eight-core Coffee Lake CPUs, which frankly is a bummer! As of now, the only selling point for the Intel Z390 chipset motherboard talked about so far is the eight-core compatibility.
What’s known about the SuperMicro C7Z390-PGW motherboard
This motherboard is equipped with Aquantia AQtion 5-Gbit NIC. No other information can be seen, except it was tested with 64 GB Micron 18ASF2G72AZ-2G3A1 DDR4 memory. For now, the launch date of these chipsets and the eight-core variants are not revealed. But since there is at least one end product listed online, its most likely most of the manufacturers have already readied some of the chipset motherboards for release soon rather than release it anytime at 2H 2018.
