BTO notebooks and portable workstation maker Eurocom is rather liberal at sharing confidential information on support forums. It was one of the first sources that foretold Intel developing the Z390 Express chipset, and that Intel is preparing to increase CPU core-counts on its MSDT (mainstream desktop) platform once again, in 2019.

Apparently, the 300-series chipset, led by the Z390 Express, will support Intel's 9th generation, 10 nanometer "Ice Lake" silicon with 8 physical cores. The generational successor to the i7-8700K will hence be an 8-core/16-thread chip. This also presents Intel with an opportunity to make its next Core i5 parts either 8-core/8-thread or 6-core/12-thread, and Core i3 either 6-core/6-thread or 4-core/8-thread.

BIOSTAR has inadvertently confirmed the long-sought Intel Z390 platform via a very untimely release of the user manual for its upcoming BIOSTAR Z390 RACING GT3 motherboard, which is based on the new Intel chipset. The information comes as BIOSTAR has apparently decided to cover both their B360 (B360 GT3S) and Z390 motherboards in a single user manual, which naturally spills the beans on the as-of-yet unannounced Z390 platform.

Some tidbits that can be gleaned from the user manual is that the maximum TDP for Intel's Z390 processor may well be in the 95 W range, as that's the maximum apparently supported (according to the documentation) by BIOSTAR's RACING GT5 motherboard. Remember that the Z390 chipset will allow overclocking of Intel's K-based processors. This motherboard is given some extra attention (and with layout pictures!) in the users' manual. It's been a ride made of rumors and leaked, poorly edited roadmaps and rushed chipset releases, but here we are. The time would always have come to us.

A screenshot of what seems to be a higher core-count CPU from Intel has been doing the rounds, brought to us by the usual suspects. This supposedly marks the first appearance of Intel's new Coffee Lake-S processors, which should feature increased core-counts - gearing them towards stealing some of AMD's initiative. If you'll remember, the red team regained it in explosive fashion with their first generation Ryzen CPUs - and AMD is looking to double down on with the launch of their updated, 12 nm refresh Ryzen 2000 series just next month.

The new CPUs should be delivered alongside a new platform, Z390 - at the moment, a mirage that's been referenced here and there, but still has no concrete evidence towards its existence. However, it's expected that Z390 as a platform will be what Intel's Z370 was supposed to be from the very beginning - but never could. The idea that's been circulating, and which has some credit (though it should still be taken with a salty disposition), is that due to Intel's need to rush Coffee Lake out the door - so as not to compete against AMD's 8-core Zen-based CPUs with their usual cadre of 4-core, 8-thread processors - led the company to rush out the Z370 release. The idea for Z370 was simply for it to deliver, at all points in the minimum requirements, the correct power delivery hardware and mechanisms for the increased power draw that comes with the added cores. But it was, as such, absent of any real improvements - it can be interpreted, basically, as a re-branded Z270 chipset platform - and there's something to that claim, definitely. Thus Z390 will be the actual, originally planned platform for Intel's Coffee Lake CPUs, with all features - however fair that is for buyers of Intel's Z370.

The first socket LGA1151 motherboard based on Intel's upcoming Z390 Express chipset was spotted on SiSoft SANDRA database. The board is SuperMicro C7Z390-PGW, a client-segment motherboard by SuperMicro under its SuperO brand. Intel is slating launch of the Z390 Express chipset for some time in the second half of 2018, following the early-2018 launches of H370 Express, B360 Express, and H310 Express.

The Z390 Express chipset adds to the feature-set of the platform, with an integrated Programmable Quad-Core Audio DSP, SoundWire digital audio interface, an integrated 10 Gbps USB 3.1 controller, integrated 802.11ac WLAN controller (with external PHY), an integrated SDIO controller (for card readers), and support for newer generation "Titan Ridge" Thunderbolt 3.0 controller.

Having hit a wall with fab process-assisted micro-architecture advancements, and facing an unexpectedly competitive AMD, there's only one direction left for Intel's product development over generations, core-counts. The company is on the verge of introducing 6-core/12-thread "Coffee Lake" processors to the mainstream-desktop (MSDT) platform in a few weeks from now; and if leaks by a popular BTO desktop-replacement/mobile-workstation manufacturer Eurocom is to be believed, the company could increase the core counts a second time in 2018, by introducing an 8-core/16-thread MSDT part.

A Eurocom representative, posting on NotebookReview forums, hinted at the possibility that the upcoming Intel Z390 Express chipset, which hits motherboards in 2018, could exclusively support 8-core/16-thread processors, which come out in the second half of 2018. The representative revealed this in context of the company skipping the Z370 Express chipset, as it lacks support for those upcoming 8-core/16-thread chips. In addition to support for new processors and possibly next-generation "Ice Lake" processors, the Z390 chipset adds several new features over the Z370, including a better onboard audio solution, integrated WLAN, and SDIO controller.

It turns out that Z370 Express won't be the highest-end desktop motherboard chipset for Intel's 8th generation Core "Coffee Lake" mainstream-desktop processors, with the company planning a higher Z390 Express chipset for the second half of 2018, according to a leaked company roadmap on 300-series chipset roll-out. Intel is launching its first Core "Coffee Lake" processors this October, along with the Z370 Express chipset. The mid-range B360 Express, H370 Express; and entry-level H310 Express chipsets could launch in Q1-2018, which is also the time when Intel launches the Q370 and Q360 chipsets for corporate desktops.
