Intel Announces Xeon W-3175X: 28-Core Processor for Extreme Workstationsby Anton Shilov on October 8, 2018 10:54 AM EST
Intel on Monday officially introduced its 28-core processor for extreme workstations that it teased first back in June. The new chip comes with unlocked multiplier and can run at up to 4.3 GHz in burst mode.
The Intel Xeon W-3175X CPU is based on the Skylake/Cascade Lake microarchitecture and is compatible with motherboards featuring Intel’s LGA3647 server-based socket. The CPUs runs at 3.1 GHz stock, but can increase its frequency to 4.3 GHz, it features a six-channel DDR4 memory controller that supports up to 512 GB and a massive 38.5 MB cache. Since the chip uses a new socket, it is naturally not compatible with any motherboards available on the market. Meanwhile, to date, only ASUS and GIGABYTE have confirmed plans to offer mainboards for Intel’s Xeon W-3175X.
The new 28-core processor has a massive TDP of 265 W and considering the fact that it comes with an unlocked multiplier and can be overclocked, that power draw may get even higher. That said, the Xeon W-3175X will require a very robust cooling system, preferably a liquid-based one. At least, Intel itself demonstrated the chip with a cooler featuring two fans and a 240-mm radiator.
Intel aims the Xeon W-3175X primarily at content creators, which is why the platform offers 68 PCIe lanes (44 on the CPU + 24 on the chipset), enough to install more than one graphics card, numerous high-end NVMe SSDs, and whatever special-purpose accelerator is required.
The newly unveiled ASUS ROG Dominus Extreme is specifically designed for use with the new Xeon W-3175X processor which is the newly announced 28-core processor, which given official specification are currently unavailable we know is going to require a large amount of power draw. To compliment this the ROG Dominus Extreme features not just one, but two 24-pin ATX power connectors along with four 8-pin and two 6-pin 12 V ATX power connectors to provide enough power. The ROG Dominus Extreme is based on the EEB ATX form factor and has a total of twelve DDR4 slots which should support for up to a maximum of 192 GB of system memory.
On the bottom half of the board there’s a total of four full-length PCIe 3.0 lanes which should support four-way SLI and CrossFire for one of the most Goliathan gaming systems going; bearing in mind that this platform is designed primarily for professional workstation users, the ROG branding indicates otherwise. The PCB is covered by a wave of armor which looks clean and featured on this is a large ROG logo. Underneath this looks to be a chipset cooling fan which it’s likely will run warm due to the nature of this particular board.
In the top right-hand corner is a set of buttons which look to include a power, reset and potentially a clear CMOS switch. Also featured is an LED debug and to the left of the ROG DIMM.2 slot for M.2 PCIe 3.0 x4 SSDs is a quadruplet of dip switches; these are most likely to enable or disable the individual PCIe 3.0 x16 slots.
This is a breaking news. We update the story as we get more information.

The picture directly above this line shows a system with a three-fan 360mm radiator.
Gratin - Monday, October 8, 2018 - linkYou need to dissipate minimum 255W at 3.1 GHZ.
Probably much more when fully loaded.
I see no other fan in the case.
It would be interesting in seeing the overall thermal performance.
Gratin - Monday, October 8, 2018 - linkIs it me or the case is not square?
What are these black pieces holding the back?
DanNeely - Monday, October 8, 2018 - linkthe case image is definitely distorted/badly edited. It looks like someone tried to combined a straight on shot with one at an angle to show the top/front of the case and did a facepalmishly awful job. I suspect the black things are hinges to attach the side panel as a door.
MrSpadge - Monday, October 8, 2018 - linkConsider revising that one:

Eliadbu - Monday, October 8, 2018 - linkat least EKWB has waterblock for it ( I won't even considered using AIO and Overclocking it at the same time)
Neoqueto - Tuesday, October 9, 2018 - linkThank god, the TDP can still fit in a single byte, phew.
SaturnusDK - Tuesday, October 9, 2018 - linkAt base clocks, sure :D
NikosD - Tuesday, October 9, 2018 - link@Anton Shilov
All the other sites are giving the TDP as 255W.
I think you have to correct your figure of 265W.
piroroadkill - Wednesday, October 10, 2018 - link"massive 38.5 MB cache".
Eh, it seems pretty small for a 28 core chip. Remembering back to my old Q9550 which had 12MB of L2 cache between 4 cores, that would equate to 84MB if things had stayed the same.
