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.
