Gigabyte will soon be launching their flagship motherboard for Intel's HEDT Xeon W-3175X CPU. The new motherboard will be based around the C621 chipset which would support the flagship processor and the first 28 core chip that Intel has to offer to enthusiasts.

Gigabyte's C621 AORUS Xtreme Motherboard For Intel's Xeon W-3175X Unveiled - Features 32 Phase VRM, Seven Full-Length PCI-e Slots, Huge Heatsink on an EEB Form Factor Design

We have seen the likes of the ASUS ROG Dominus Extreme which was recently the only board you can purchase for the Xeon W-3175X. It looks like the only other player that will be offering a C621 chipset based motherboard will be launching it soon. Yes, Gigabyte is one of the two motherboard makers who will be offering a C621 chipset motherboard. Other board manufacturers have so far not confirmed their plans for a C621 chipset motherboard. The reason could very well be the price of these products which is completely insane. The ASUS ROG Dominus Extreme motherboard goes for $1799 US on Newegg and that is excluding the $3000 US processor, which is the only one you can purchase with this motherboard.

C621 AORUS XTREME now has a more powerful VRM design and richer platform I/Os. It is the ultimate platform for those seeking the most advanced computing power for tasks ranging from digital content creation, deep learning, extreme gaming hosting to powerful medical imaging calculation, biological genetic analysis, energy exploration, astronomical science research, and much more.

Now talking about the C621 AORUS Xtreme, it looks like AORUS has gone all out with their C621 chipset-based flagship design. The thing I like the most about this high-end series is that each of the OEMs can showcase their engineering and technical prowess in such products. The ASUS ROG Dominus Extreme shows how far ASUS is willing to go with their premium and ultra high-end design while the C621 AORUS Xtreme shows the same for Gigabyte.

Feature Highlight of the C621 AORUS XTREME Motherboard:

  • > Supports W-3175X Processor
  • > 6-Channel Non-ECC Unbuffered DDR4, 12 UDIMMs
  • > 32-Phase IR All Digital VRM Solution with PowIRstage
  • > 7-slot Multi-Way Graphics Support with PCIe Armor and Ultra Durable™ Design
  • > Dual Intel i210AT + i219LM GbE with High ESD Protection
  • > Ultra-Fast U.2 with PCIe Gen3 x4 Interface
  • > Supports 2 SATA Disk on Modules for embedded system storage
  • > Immersive Gaming ViBes with ALC1220-VB and WIMA Audio Capacitors

If you take a close look at the motherboard, you'd know that this is the same product that AORUS first showcased back at Computex 2018 which was used for a public demo during Intel's keynote. The motherboard makes use of a 32 Phase IR Digital VRM design and houses the power delivery under a huge finned heatsink that covers the entire upper portion of the motherboard. The PCH is cooled off by a heatsink that is an extended section of the upper heatsink and features a similar fin cut design. The AORUS logo can be seen on the PCH heatsink with silver accents and the obvious RGB touch through Gigabyte's RGB Fusion technology.

The LGA 3647 socket is surrounded by 12 DDR4 DIMM slots which support memory with speeds of up to 4200 MHz. The motherboard houses a total of seven full-length PCI-e slots and the AMP-UP Audio design is also a prominent feature of this C621 motherboard. There are at least 8 SATA III ports and a single U.2 port on the board. Of course, feeding the motherboard with power would be a huge task as the motherboard requires four 8 pin power connectors and a single 24-pin ATX connector to boot. The motherboard can deliver up to 1600W of power directly to the processor hence the overclock showcase.

Just for the sake of their presentation, Gigabyte once again showed the chip running at 5.0+ GHz with a water chiller providing the cooling support. The chip was tested in Cinebench R15 and had scored over 7200 points.

The chip was also compared to a dual EPYC 7601 (64 core/128 thread) setup which scored around 6000 points and a Xeon 8126 and dual Xeon 8170s (56 core/112 thread) setup which scored around 6500 points. There is also the Core i9-9900K running at 5 GHz in the benchmark which scores a tiny 2200 points when compared to the higher-end workstation parts.

There's no word on the pricing or availability yet but considering what we got with the ASUS ROG Dominus Extreme, expect the C621 AORUS Xtreme to cost around $2000 US with a market launch soon as the processor (Xeon W-3175X) has been out for a while now.
